I'm an electronics tech , makes sense , and I've run into this type of problem before , but your video makes sense and I think cured my problem , 10 minutes and no cost , got my fingers crossed, thank you so very much

thank you for putting this out there I am a auto technician in Nebraska and this just saved me a lot of time and my customer a lot of money

I wish people would make the distinction..Grand Cherokee and Cherokee are two different vehicles.

I have a 98 grand Cherokee and have been stalling when I'm coming to a stop. A friend showed me this video and I took it to another friend who is a master mechanic he ran the diagnostics and all was well so I showed him this video and we shortened the screws now it works like a charm. It really does work! Thanks for posting this.

TOTALLY WORKED!!!! I unscrewed both halfway. No need to cut the screws or replace. It only took a few minutes and it worked like a charm!! Thanks for this video. Been trying to fix this problem for a while.

My brother started having a cut off problem but thought it was the coil so he replaced but it wasn't, it was still shutting off. We checked youtube for a problem and everything pointed towards the Crankshaft Positioning Sensor so we changed it, but nope. So we checked out your simple fix without the soldering, just shortened up the (2) T-15 bolts holding the inside board to the outside and wallah. Was getting a code but it even fixed it (0) codes now. Thanks.

That will work for a couple years. Watch the other videos on DIY PCM fixes. you need to solder the connections on the inside cover of the harness plug plate. Factory job is shit. Did it myself. Works great now. Saved $350. Look it up.

Reminds me of the hell I went through 12 years ago. Jeep Grand Cherokee, 1996, stalling. Did some research and found out that it's the computer. Took it to the Jeep/Chrysler Dealer. Yes, DEALER! The new computer that had to be programmed for that particular Jeep (bull shit) cost me $700. New computer in, and the dealer mechanic shows me the three plugs on the computer. As he pressed them down, the engine stalled. Looks like the plugs are bad. Can't buy plugs anywhere. So I did more research and found out that a guy cut off his three plugs and soldered every wire to the computer. So, I did that. Took me three days in my basement to solder every single wire to the correct pin on the pcm. I bought every female and male connector pin from Radio Shack and a bunch of shrink tubing. I had to tell the guy what I was doing. He kept asking me, probably thinking I'm building a frikin bomb or something. So, I put the pcm back in the Jeep with the new soldered wires, connected the soldered wires to the cut off wires on the Jeep, (took me a few hours) and it still started stalling. I was about to flip. Found out that the new computers are crap. You bend them or press them and the engine will stall. So I unsoldered every friking wire and reconstructed all three plugs back like they originally were. Ordered a used Jeep pcm from a junkyard. The pcm was old but looked different. Looked solid, not a tin can like the one I just bought brand new. Without programming it, I put it in and it's still working today. 12 years baby and I refuse to get rid of that old Jeep. Running like a tank. The End. :)

I'm going to try that tomorrow. It's not gonna hurt to do it, man I've tried almost everything but this! Thanks bud

I fixed it! Use sandpaper and Pine-Sol (with a toothbrush) to clean the ECM terminals. Works great now...

Hi i have a question i have a 2002 jeep grand cherokee n our gauges died n my bf replaced the negative terminal n the jeep stalled but than it started but the gauges were still dead so the next day he cleans the positive terminal n now the jeep starts but stalls even with foot on gas. Would that be considered the same thing as the jeep u were working on?

Good Video. Thanks for posting it. I have done this, ran the gauntlet by changing everything out even the screws....Tried to open the OEM ECU and found cold solders everywhere. Ended up getting one from Autozone 2 years ago and it has worked fairly well. I am now back to stalling, having issues @ 50mph ect. There have been electrical gremlins all over this beast. I am determined to find and kill all of them. Love the Jeep...just not the grey hair it gives me. " Its a jeep thing!"

same thing happened to my jeep 2 years ago. it ended up being the crankshaft sensor. but it happend again this week but this time it was different because my jeep would not last running for more then a minute before it shut off. then i would try to turn it on after that and it would not turn on until i waited an hour for it to cool off. what i did was unplugged my battery and disconnected the ecu connections and cleaned the contacts with electrical spray cleaner. i also unplugged the extension connection for the crankshaft sensor thats on the back of the engine by the firewall and cleaned that also. i also went into the fuse box thats by the engine and switched the asd relay with a different one. it turned on and stayed on. im on day two and it has not turned off on me. hope this works for who ever needs it. ( 1999 xj)

hey oz! my GC 2009 engine turn off while driving! do you know what its going on? i hookin up the relay with the computer and still shutting off

that's awesome man ive been having this same issue all week, I was doing the same thing with the brain and jiggled the harness and BANG she shuts down,..

Great info, Thx for posting

it works thank you very much. only difference I left them out. 96

I have a 96 gran cherokee v8, but the PCM are different, all the case it´s aluminium and bends in the lower side, this type of pcm can´t be repaired ?

I have a 1997 grand Cherokee Limited 5.2 V8 and have been having this Stalling problem. I replaced the idle air solenoid and the problem still exists. I just removed my PCM and it does not have the screws shown in your video. So I guess I’ll move on to the next potential fix. Will have to look at crank sensor and throttle position sensor and related wiring

The problem is cold solder joints in the PCM. The reason the screw change works for a while because it pulls the connection. I tried the clamps, zip ties, you name it. So called reconditioned PCMs usually have the same problem. I pulled mine, took the cover off cut the potting material all the way around then heated the back with a propane torch till the board would come out. Spent a couple hours cleaning the potting material off a strip about 2 inches or so across the middle of the board. This is where the pins are soldered in. Near the back of the third plug I found three bad solder joints. Resoldered them, laid a thick coat of clear silicone and reset it back in the case. It was cutting off at least 3 times a day, it's been a week now and not even a single skip.

Cool video! Helpful! But I tried this years ago and it never worked, no matter what I did. I replaced the ecm twice from an outfit in Florida. Didn't work either. I spent weeks troubleshooting my electrical issue. Turns out that the ecm's were a bad design, and Chrysler knew it. So it was redesigned for 1999 using an all aluminum, solid body with a single circuit board (instead of 2 separate boards as yours has). So I ordered one through Autozone. It's meant for a 1999 and up. They programmed it to work with older models, and mine has been running flawlessly for about 3 years! If you are having stalling issues, it is more than likely the horribly designed ecm for the older models! But you're right, wiggle that third connector, sometimes really hard. And if it begins to stall, stutter, or it dies, the ecm has bit the dust. Replace it with a newer model ecm programmed to work with your year! It will save you the frustration and headaches. Don't believe me? Come check out my meticulous engine rebuild and troubleshooting of this notorious Jeep problem. Best of luck to you all!

I have a 1993 jeep grand Cherokee Laredo V8. As long as I keep my foot on the gas it will stay running. Soon as I take my foot off the gas it turns off. Any idea what the problem could be? My search on youtube has lead me to believe it is my PCM. Would hate to replace that and the problem could be something simple or something else.

Hi all, A big THANKS to you all for posting your videos on RU-vid or your comments on the countless forums to help people out with their problems. I'm posting this to possibly help others out there that may need it, because I found that everyone had slightly different issues around the stalling problem. Mine was different also. I have a 1996 Jeep Cherokee that had a stalling issue. It's fixed now, but I'll let you briefly know what happened. My Jeep was fine when it was a cold or cool temperature but would always stall when it got to a normal heated operational temperature and stopped at lights or backed up traffic at idle. It wouldn't start for at least another 30 minutes until it had cooled enough. I then realised it was always in D-drive when it stalled, so I tried flicking it to neutral every time I was stopped and it wouldn't stall until I got to my destination and tried to start it straight away. Again i would have to wait for it to cool and then it would start. After stalling I checked the diagnosis codes by turning the ignition to the 2nd position 6 times and waiting for the codes to flash. That told me to replace the coolant temperature sensor, the crankshaft positon sensor, take it to a mechanic for diagnosis and the completed diagnosis code 55. I disconnected the ground battery terminal from battery and started with the cheapest of options which was the coolant temperature sensor. After replacing the coolant temperature sensor and connecting the battery, I then checked the stalling issue by driving around for an hour and leaving it in drive and it stalled and wouldn't start for 30 minutes. I then decided on the crankshaft option so I disconnected the ground battery terminal, changed the crankshaft position sensor and tested it also by driving around for an hour and leaving it in drive and it didn't stall. Problem fixed. I then checked the diagnosis codes again and no codes came up, besides the code for less than 50 key starts since the battery was last disconnected and the completed diagnosis code 55. Regards Kurtis

I have a 1993 Jeep Cherokee limited. It has stalling problems and will shut off I have a micro mechanic is there a place to plug it in and do they work

i did that but my issue was the battery negative wire was loosening wires from the back of connector. i rewired it up and she works like a charm! could be low power from loosened wires in back of negative or positive.

I have a 98 JGC doing the same thing, it stalls at any speeds, inside lights flash. I pull over and usually starts right back up. Problem is i tried wiggling that connector and it didn't die, i guess i should go ahead and try this and see if it will fix my problem.

I'll try this on my xj tomorrow I hope it works

I have an 01 Jeep Grand Cherokee limited and it is doing the same thing.. I took it off but only problem is it doesn’t have the two screws like this one has.. so what do I do? I desperately need help!!!

Well I have a 01 Jeep Cherokee that 4.0 has been though hell and back and now when I’m driving it’ll drive fine but when I come to a stop light it will stall and it will take a second but it will start up and go and do the same thing and also sometimes the CEL will come on and one time it will say missfire in cylinder 1 or cylinder misfire 2 on different days does anyone know?

I have already replaced and my jeep ran great for a day it was a dream come true rpms didnt go down past 500 rpms then Friday it stalled on ne as I was going to the vape shop iv replaced the altnater and com nothing has worked im beggining to suspect its the battery cause the altnater abd battery work together on thses trucks but I could be wrong so im leaving to go home here soon if you could tell me what to do to not get in to stall I cant fix it at the moment so plz let me know guys if anyone has any advice plz let me know I have a 15 minute drive that could turn it 3 hour drive

My 97 laredo had this problem. Bought a new computer and sill does it. Please help... Fuel pump??????????

This might work I'll let you know shortly. We had the same problem in my 93. We even replaced the computer. We shall see

thanks for the info, I have a 97 grand cherokee 4.0 that was stalling with no codes showing and when I wiggled the plugs on the pcm it would stall. I took out & shortened the 2 front screws a 1/2" as stated in your video and problem solved. thanks again...

Thank you for your Video. I'm in Australia and the Jeep Dealers, they are called "Steelers" quoted me for a replacement of CPM for $A 3500.00. I'll try your suggestion next week. We'll see how it goes.

My 2000 Jeep Grand Cherokee Laredo my PCM connection is bad I went to salvage yard got more clips they fit loose so I taped them up it made them fit tighter I think I need to find new clips for it .

I have a 1998 Grand Cherokee 4.0 with a slight sputter problem when I start it then it goes away in about a minute and runs fine until I turn it off and start it again. It doesn't do it all the time now that the weather is in the 80's. In cooler weather, below 80 degrees it sputtered every start up then went away. No check engine light on. Help?

my 2000 jeep grand cherokee just started to shut when i come to a stand still at red lights . It drives fine when consistentley driving only happens when im at a stop and foot is on the brake waiting for the light to change. the first time it happend it took 5 min to turn over. yesterday it shut down on me twice but fired up right away when started again don't know what the issue is anyone can help?

I have a 2002 jeep grand cherokee rough idle and stalling changed the crankshaft sensor cam sensor oil pressure and air filter new plugs and ignition coils it's a V8 4.7L and suggestions?

Question Where can I buy smaller screws for this my is doing the same thing.

was hoping this could lead me to a solution for my '00 Laredo, but the computer on this model does not have the two screws which are discussed here. Going to have to do a couple resistance tests on the clutch and crank position sensors first to eliminate those then that will probably point to a bad computer if those check out.

Would this quick fix also work on a 94 Jeep Grand Cherokee Laredo??

where is located

Hi im having a problem with my 1999 Grand Cherokee runs great until it gets warmed up then it is liable to stall at any time and when it does the sentry key light comes on and check gauges comes on all other gauges go out and will not crank back turn switch off and same thing no gauges working a sentry key light and check gauge light if you wait 5- 20 minutes it will crank back up i have plugged my snap on scanner in and no codes found so what do you think the problem is i really don't want to just guess and start shoveling money into like computer thanks.

In my case (and probably many others) 99 Jeep Cherokee Sport (XJ, not Grand Cherokee) 4L 6cy auto, the computer is sandwiched like a taco. One piece of aluminum wraps around the computer components. It does not have plates like that. The only way you can open it is to bend it open. I bent mine open, checked all the solder points, bent it back with a vice, sealed it with gasket maker, cleaned the contacts with contact cleaner but it still shuts off randomly, even while driving like 50mph. Next I will change out the Crankshaft position sensor. So for any that have this type of computer, try changing the CPS first, rather than bending open the computer for no reason.

I have a 2001 Jeep Grand Cherokee Limited 4.0 having stalling issues. When I’m at a stop it will shut off. Also will shut off while backing up in reverse. Shifts funny some time also. It not showing any codes and there no lights on dash. I did a fresh tune up, new throttle position sensor and also put in new pcm. Jeep still having same problems. Any ideas what it could be?

Any idea why my Jeep will shake while brake is applied in gear? I put in n or p and it's fine.. just in gear it shakes..

Doubt that is our problem on our 1998 Jeep Cherokee..this is a 'keep on going' vehicle, never breaks down or has mechanical issues until now. It has been lately just loosing power as though it is stalling, but then when we take our foot off the gas it recovers. Yet today it finally stalled...we pulled over and it did start back up...so we do not think it is a fule pump issue..how about fuel injectors or fuel filter? Mayb water in the gas...probably not as one time it stalled when it had 1/4 tank, then we filled it to past a half tank and it stalled again...any thoughts out there?

SO ITS BEEN 2 YRS ROUGHLY INCE U CUT THE LIL BOLTS DOWN IN HALF OR ABOUT'S... ON THE PCM OF THE 98 JEEP THAT WAS STALL'N OUT..... HAS IT CAME BACK W/ THE STALL'N OUT R ANY OTHER ISSUES'S.......

Hey do u wsnt to work on my car

I have a 89 jeep cherokee sport with 4.0 straight 6. It keep stalling on me at random times. i have power to everything but it will just crank over n over. if i let it sit 10-15 minutes it starts right back up but will do it again shortly after again. I really love this jeep but its costing an arm and a leg replacing parts to try n figure out what it is, any HELP would be awesome!! Thanks

Hey Oz, Could this issue exist with a 2014 Jeep, or is it something chrys corrected? I have a 14' Cherokee Sport and have been stalking out at odd times. It started stalling shortly after starting the engine- usually a mile down the road after I came to a stop. I noticed that if I left before the violent was over 150 degrees, it would stall in that timeframe. Assumed I needed the coolest drained or topped off. The past few drives, it has stalled each time I came to a complete stop. Power is fine it seems, and I don't have the issue when it's running at full (highway/above 30mph).. Usually takes a few tries at starting- like nothing kicks except power- then I give it some time, it will struggle but get started and run "normal ".. Seems to be occurring almost every drive now.Any ideas? Could this be related?

i have a 89 jeep cherokee and it starts and idles for about 3 minutes then sputters and dies replaced cat. and fuel filter and stills die and tested the fuel pressuer and said it was ok please help with congestions

Mine is stalling. How shortening a screw can work? I don't know but I will try it.

or a couple washers

It worked for me. Jeep ran 1 1/2 years after I did this but started stalling again. May change PCM now.

OK silly question. Do you just wiggle or pull out all the way?

my 96 Cherokee sport keeps stalling randomly too 😢 tried to fix it replaced the crankshaft position sensor and then it was fine for a day and a half then it stalled again right after I pulled into the street

i have a 1985 amc jeep cherokee and it shuts off when i come to a stop but starts right up and drives fine when rpms up. Any tips??

i have a 99 jeep cherokee. same problem, intermittently shuts off, runs rough, a couple times just shuts down and wont start. everyone with this problem should jump the ignition switch red and blue wire. put a switch between the jump so you can turn it off and on. drive the car with the switch on and see if this takes care of your problem. if it does then its your ignition switch, not the key tumbler, but the switch box that the wire connector plugs into. about a $40 part. i went through a lot cleaning grounds, new coil, cap, and wires, checking wire looms and it ended up being the ignition switch. my problem was intermittent so i put the jumper switch on and drove for a few weeks without a problem before i spent the $ for the switch. hope this helps someone

Great video, thanks! However, as a mechanic/technician, don’t you want to fix the root cause? Why does shortening the screws “fix” the problem. Actually, it only fixed the symptom. I understand the problem may be cold solder connections from the jacks to the terminal board of the ecu. I’m taking my 98 GC ecu apart today to see why shortening the screws alleviates the symptoms. I’ll also resolver all of the terminal jack connections.

can anyone confirm this

Mines a 95 i dont have a obd2 but it won't start itll pit sputter and if and when it starts it runs and fires on 3 cylinders

Hi i just watched your video and that's exactly what happened i wiggled the 3rd connector and it turned off. Now you said if if it works you will post the video online, well am i to take that because this video was posted that changing the screws to shorter ones did in fact fix the problem? Can you please reply back so that i know thanks!

I clean the idle air control works fine for a week and back again to rough idle and dies out after a while!!

Wife’s 2015 Jeep Grand Cherokee Laredo 3.6 has stalled out a few times. In the beginning, the touch screen display would short out at times. If most know, when that touch screen display shorts out your climate/temp/Ac controls won’t work. They’re tied in together. Jeep knows of this problem. They can act stupid all they want. I’ve been hearing for the past 7yrs it’s the poor quality solder joints in the brain boxes. Don’t know how truer this is.

i have a jeep cherokee 1999 problems to unlook the doors whit the kyes remo control

Help my son! 1997 Jeep Sport Jeep. Jeep is stalling out. His ex uncle has put in some many electrical stuff in the jeep. My ex husband there is a short in the electrically system. My ex and I don't know where to turn. Help!

did this fix work

Yeah they are different cars but the 4.0 is still basicaly the same, and this stalling issue is a VERY common problem that drives people nuts. Unfortunately he did not say why grinding the screw down solves the problem.

i got a 1994 jeep cherokee laredo and the problem is while im driving it all of a sudden it wont excellerate. pedal to the floor, pumping for gas then when it catches it takes off. It keeps doing that like every 2 minutes. Can you tell me whats wrong with it?

Can anyone see my be video on my jeep it's a problem I've had for years with no luck fixing and I feel it's maybe the pcm

My Cherokee shuts off while idling or at a red light I've heard from crankshaft, leaking air valves to PCM 😕

Why not use washers..?

this turns out to be a temp fix. the solder connections inside the pcm have likely broken. very common on these models. resolder, long term fix.

se especifico

i bought one of these on ebay remanfactured thru a company in Florida for 199.00 with free shipping. Theres another company that will remanucture your existing pcm for 121.00

So did it fix the issue

As soon as i saw this video i called my auto parts and order one $260 got it in 2 days AND MY JEEP STILL HAS A ROUGH IDLE AND DIES ON ME.it did absolutely nothing so back to square 1 on trying to fix my 97 laredo.

My Mother had a 2010 Patriot that had a stalling problem. Once I was driving it home and not stopped. I could feel it trying to cut out.

almost said he got the harness off another customer, then switched and said guy who was selling it 1:40 guessing he charged this person for a new harness? LOL

How to fix 2000 jeep grand Cherokee 4.0l crank over won't start.

How did this supposed fix work? What was the mechanics of the shorter screws in fixing the installing issue? To me it sounds the equivalent of putting a marshmallow under your distributor cap and , WA LAH ! Lol

my cousins 95 jeep that runs good on the street at regular speeds, however when he gets on the freeway/highway and reaches speeds at 60 and above it dies for no reason, he just waits 2-3 minutes and it turns right back on..Does anyone know what it can be????

That's why you go back to the other four mechanics. And hand them papers for lawsuit for damages, for incompetence

Just bought new one. Pre flashed 260.00

Tried that didn't work any other ideas

I have the same jaguar hahah

be specific

I am looking for the Jeep Cherokee in the video....not seeing one

I bought a 2019 JGC, I have less than a 1000 miles on it and it's stalling at every stop light it will then automatically start up again.

Stop, don't buy the PCM or computer for your Jeep. I have a 99 Jeep Cherokee Sport. I could be doing 70 miles an hour down the highway or sitting at a red light and it would just die. When it would die while I was driving I could put it into neutral gear and it would start immediately and I could go on about my Merry way basically thinking what the hell just happened. This went on sporadically for a couple weeks until the Jeep would not start immediately while driving. I would have to pull off the side of the road and wait a few minutes or even a few hours before it would finally decide do not hold me hostage any longer and would start up as if nothing ever happened. It went from doing this once in a week three times in a day. I replaced a couple of sensors while watching videos. It wasn't until I replaced the crankshaft sensor and soon as I did it was like a miracle everything started working as normal. I'm 2 months into this fix and it has not stalled at any time not once. I'm just saying this because I crankshaft position sensor $65, it's going to be a lot cheaper than replaces that computer. I bet you. Took me about 30 minutes to put it on myself it's really easy to find. On the Cherokee Sport it is on the driver's side of where the transmission bolts to the engine. Mildly difficult to get to but you can do it if you're I do it yourselfer and it solved my problems without buying the computer. Not saying that yours is not a computer problem. Come to find out there's several different components that can cause this stalling problem and I couldn't wrap my head around starting with a computer first. Perhaps I got lucky and didn't have to buy a buttload of sensors to finally buy a computer and it got fixed. With several components that can cause this it is a roll of the dice I'll give you that. At least I rolled the dice it didn't come up with Snake Eyes lucky me I guess LOL

The problem is broken solder joints inside PCM, screws pushing against board and heat expansion opening broken joint, causing stall. Open up, remove goop from solder joints of connectors reflow solder, problem solved.

What is that clicking noise in video? It's a little irritating.

So you make a video and don't tell us what fixed it ??

Mickey Mouse isn't in this video? This is no fix......................................

⁰pop

That is a GRAND CHEROKEE, not a Cherokee

my 99 jeep tends to shut down, after it gets hot...and then I can wiggle the middle harness, and get the car to start up again, rather than just wait for it to cool back down... I am thinking that the heat is causing a soder point to expand, and by wiggling it, I am able to gain continuity again, so.....this decreased pressure on the circuit board, is going to reduce the heated expansion, that is causing the shut down...I am going to try this fix...back out the screws, then warm up the jeep, and see if I can no longer get that wiggled harness to shut down the engine. Next step would be to have the board resoddered and inspected for continuity?
