Lmao they don’t make ‘em anymore and Amazon doesn’t sell them. Just called Ford and it sells for $160 for the whole assembly. Found the rubber elbow at Napa for $30. This video helped a lot. Thanks dude.
Here is one on this problem that no one that I have watched covered. I had rough idle a PO171 code and stalling when put in gear, I check every sensor looked high and low for a vac leak watched over a dozen video and could not find my problem. everything checked out as good final we figure it out a clogged fuel filter was not allowing enough fuel to get to the engine a long day of pulling out our hair ended with the very simple and cheap fix of a new fuel filter. The one important lesson I learned was start with the basics and branch out from there.
I had a rough idle in my 2003 Explorer. One of my best friends, who is a certified Ford mechanic, pulled the codes and insisted that it had a cracked intake manifold. After checking the video, I located the rubber elbow and sure enough.. It was the exact same split. Since it was a Sunday and I am 2 hrs from a parts store... I cut a piece of washing machine hose and Voila!!!! Fixed!!! I then disconnected the battery for 15mins and the Check Engine light reset itself. Thank you very much.. All is good again!!!!
FordTechMakuloco i have a 96 4.0 acting the same way but im not finding it on the side you are in the vid is there a different set up also? I found something similar on the other side
i am hearing the air ,why i havent gotten to it yet ,lol. ,reset the code pull neg ground off battery place a piece of cardboard under clamp to insulate from reconnection.using a wire w/alligator clips on both ends touch the ground cable to the hot cable and battery post 5 seconds.only way to erase memory according to one video .good video i havent gotten to the leak truck is gonna be fixed soon i am sure of it now cause i heard real air leak and my idle mostly is problem almost like gurgling
Well, You saved my ass again! 4 years ago I followed the 4 part video of timing chains in my 1998 Explorer 4.0 SOHC motor and its still going strong. Now I went back to your videos because I had the P0171 & P0174 codes. Been working on it for a week. Tried the relearn strategy, Still ran up and down. Watched your video and sure as shit that was the problem. Changed out the hose, Test drove it and no more racing engine or dying at a light. It was so bad that sometimes coming to a stop light the tranny would bang so hard. And yes I did do something stupid, I changed the IAC motor thinking that was the problem. Your the best!! Subscribed to you for 4+ years now!
Thank you so much! My 2002 Explorer would not run on its own while idling and found the problem in less than a minute of having the hood up. My elbow was disconnected from the hard tube. Popped it back on and put a hose clamp on it for now. You're the best!
Thank you so very much, your advise enabled me to locate the elbow and find that it had completely detached from the engine, reconnected and idles perfectly.
OMG. I had gotten a diagnosis of intake manifold leak. I was prepared to just scrap my '03 Sport Trac. YAY! $120 fix from my shop and I'm back in business. THANK YOU!!
Thank you. I had to clear 4 error codes so my GF's 01 Ford Explorer Sport would pass emissions and I did not notice this cracked tube when I was diagnosing the last two 0171/0174 error codes until I watched your video.
More Explorer vids please. Trying to keep mine on the road it's a 94 Fort Explorer Eddie Bauer 4x4 4.0L it has 312,000 miles I love it and I learned a lot about motors
Is that thing still on the road?? You have the OHV or the Dohc like he does? I got a 97 ford explorer OHV and im at 366xxx km and just replaced the head gasket but now im getting engine too lean codes but im hoping its just my hoses or a broken o2 sensor
ill try not to be long winded here but in a nut shell, every thing you stated regarding the codes, symptoms cause and repair were exactly what i found, so thank you,
I own a 2008 fx4 4.0 ranger that I purchased about four months ago and im just trying to get as much information as I can about these motor, I'm a new subscriber, thank you for your helpful videos
Changed out the valve gasket on my wife's 2008 Ford Fusion today. Did exactly what you said in your video, felt very confident. The job took me close to an hour. Took my time taking everything apart and cleaning/ inspecting. Waited for about 4 hours for the RTV to cure, then ran the engine to operating temp, found no leaks. Went for test drive and double checked the valve cover for leaks. Wonder how much a mechanic would charge me for this job! Excellent job on your video!
My 2003 Ranger 4.0 never had a rough idle just a sudden CEL for P0171 and P0174 lean codes. I checked my PCV elbows and didn't see any cracks or holes. I pulled the front elbow, the one in your video, and found a small hole on the underside. I replaced it with a elbow I had, cleaned the MAF and cleared the codes. I hope this fixes the issue.
I have an '03 Sport Trac, My truck was wanting to die while sitting at idle for a long time. I came across your video, while searching for how to change the O2 sensors. I went and checked the elbow, and low and behold, the elbow had a split in it. The only thing I was hoping for in this video is showing the exact placement of the complete hose, removal and install. This video just saved me $300. Mechanic didn't even check the elbow, just went by the codes and insisted it was the O2 sensors.
Thank you very much for this info. I have a similar setup on my 2002 Ford Ranger XLT 4.0L. One design I don't like is how the PCV has to be mounted to at port at the end of the Left Valve Cover. A Mechanic had cracked that PCV mounting port off the valve cover and it cost me plenty to have that valve cover replaced. So, for me that PCV can be very costly to changeout, if I have to change the valve cover too. I changed lots of PCV valve, but I don't want to change this one.
OMG you just solved a problem for me that I have been looking for for about 4 months now. Although I am a female I know a little bit about cars just not enough and I've done everything but that! wow, I wish I would have found you sooner, I have found you now and yes I subscribed, thank you so much you was truly a godsend for me right now and thank you so much for the great detailed instructions, us women truly appreciate that!
Another reason it could be hunting for idle other then PVC or TPS or IAC on cold starts is the Timing chain tensioners, there are 2 of them an upper and lower..this was my case.
I miss my OHV 4.0. 174,000 miles and still didn't have to do any repairs. Still ran like new, ran better than my cousins POS chevy s10 4.3 with 180k. White smoke, crusty oil residue, ran hot even with a good cooling system. Burnt oil too and started getting rod knock.
Great tip. I've had my '03 SportTrac since '05....Pretty decent and dependable vehicle. Replaced this a couple of years ago. You're exactly right, from my experience dealing with mine, really just small components fail from regular wear and tear. The most annoying things were the emergency fuel shut off, and that darn t-stat housing (X3), With regular maintenance the hard stuff been held at bay so I've been happy. My wife just bought a '14 Explorer 3.5 V6. We'll be lucky if it's any where near as good of a vehicle.
Thank you for your videos, they are very helpful. Ok,,, 2 things here. 1st, this is slightly different info here. I have a Ford Explorer 1998 4.0, my PCV valve is way in the back of the engine. It took me a while to locate it. It's also very hard to get to it. Also, Thank you Todd Picklyk, That was very helpful info, disconnect the battery for 15 minutes and it will clear the check engine light.
Thank you for posting this. I was having a rough idle and noted the P0171 & P0174 lean codes, When I looked at the hose, I was surprised to see that it looks almost identical to your cracked hose. You have saved me some major headaches. Thank you.
Love the channel it's already saved me a butt load of money!! I'm not a huge Ford fan but seems I'm always stuck in one😫so this is really helping me out I'm having a code come up for 02 sensor bank 2 that I suspect is a bad cat or 🐈 🐈 🐈 I'm really wanting them deleted but don't want the bad sounding exhaust or codes still looking for a good cat delete video where everything turns out ok!!
Do you think an imperfect valve cover gasket could cause the codes also? I know it needs to be replaced but I’m hoping the codes will go away after I change it.
I'm working on a sport trac now and it had a rough idle so I replaced the spark plugs and one of those was broke but it still has a rough idle so I will check this out
Encountered this exact same problem on my cousin's C5 Corvette. Very similar design, and it collapsed in the same way. Idle was hunting and rough, stalling occasionally. Was hard to find because the intake tube opening is pretty close to the throttle body on those and it masked the sound. Replaced the broken elbow with a scrap length of fuel line I had in the shop as a temporary fix. That was about a year ago. Still running fine that way.
Have you ever replaced the fuel rail pressure sensor on this particular vehicle-in the video? I'm trying locate the sensor on my 2003 Sport Trac (4.0 OHV) but I can't find any videos covering my model year(2003). Any help is greatly appreciated---thanks.
Mine's somewhere between rattle out and just old and decrepit.... Hopefully it's warm enough before work tomorrow to get hunting for the individual cause... I know one is near the power steering and transmission cases, and there's gaurenteed a few other connections from how long it's had this bad fan in there for.... Dang ol previous owners
My explorer does the idle up/down surge only in the winter, but not the summers... Would this be the problem? I'm not near it right now so I can't check it... but I was told it was the IAC also. Before I get parts and drive to it could you reply?
I recently bought a 96 explorer. It appears as though I either don't have the same elbow or I am struggling to find it. My engine scavenges at warm idle and I believe I hear a faint hissing, it also is throwing a P0133 code. Tried spraying carb cleaner around the entire intake manifold and vacuum lines and didn't detect any change in idle. Any help or ideas would be great! Thanks.
I have an 2001 ford explorer sport track 4.0 v6 I have replaced maf, idle control. It sits at idle then dies, check engine light on. I went and had it checked it said running to rich.
It would of been nice to actually watch you replace it, you say easy to just fish it out but I would like to see and where it goes it back, best way to get to that PCV valve and show to replace the valve, cant find 1 video...PLEASE post one if you could, definitely be much appreciated!! Thanks
i spent hundreds of dollars on lucas high milage. additives. oil stablizers. car runs silentlike a prius. and its as 2003 ford explorer with 226k miles with a new tranny new radiator new water pump new starter new spark plugs new bAttery. welded exhaust . new tires brakes rotors calipers and oil changes at 2500k ....
I have a 2002 Explorer with the same problem. I bought the PCV elbow tube {Motorcraft KCV190}. The other problem I am having is, I can't seem to located where it goes.
Thank you for taking the time to make this video. I have a 2001 sport trac with the 4.0, and I have been hunting a idle issue for almost a year. From what I understand there is a job1 and 2 for these engines. And I cannot find this hose on my engine, I do see the plastic hose that goes to the rear of the valve cover, but no rubber hose on the front of the engine. Do you have any idea's for my engine? It runs ok, but sometimes when you put it into gear it will actually die, and start back up again after restarting the engine. I am getting horrible mpg at only 13 mpg, and have been for almost a year. This thing is driving me nuts. I have cleaned everything you can think of, and you could eat off of my engine. I am crazy about maintaining my vehicles so any oil leaks are fixed as soon as found. But this vacuum leak has been evading me. Any help would be greatly appreciated, one last thing the truck is not throwing any codes and never has. Thanks again.
@@SBS_Auto I purchased it with low miles almost 20 years ago now. I did finally figure it out, the problem was the idle control sensor I think it was called. It's right on the top of the intake in the center. Took about 3 minutes to switch out and it's ran perfectly.
Assume! Nailed it! My 03 Ranger XLT suddenly started running rough, nearly dying while idling and unable to rev over 2000 will accelerating. Seemed like it was running out of gas; it was not. Then started running better after. No check engine lite and no codes. Change fuel filter, checked fuel pump related fuses and relay. Everything OK. Just drive it. Now, two weeks later, it throws two codes: P0171 and P0174, right and left banks lean. The Chilton manual is pretty much useless for this so did a google search for Ranger P0174 P0171. Bingo! The first hit was not quite right so checking the other hits lead me to your video. Great video and thanks for the tips.
I have a 02 f150 5.4l sohc wont rev over 2000 rpm when at full operating temp just put in new plugs injectors and coils I removed cats and still doing it fuel pump and fuel filter brand new also
I haven’t got my codes checked but I have a 95 explorer and I believe it is the same problem I changed the spark plugs and still was running funny so I’m hoping it is a vacuum leak
Hey Brian, I am most likey off topic here, but I'd like to know how to get a good front end alignment, repair/replace child door locks and headlight alignment. was given 2000 explorer XLT. You could say a rolling dumpster, it was and still is in need of a lot of TLC. Yesterday the engine ran erratically, and died when wife drove to work. She thought it may have been overheated. She added 50/50 mix antifreeze and it appears to be ok. However, after viewing video, I will check that tomorrow. I am unable to drive, and apprehensively must ride in it to Dr.office. It seems squirrly on the road, one slight overcorrection scares me a bit, much like a willis army jeep. Is this because of the wheelbase being short or incorrect tire size? All 4 are the same, just smaller. Thanks for videos, and your time/expertise.
great easy explanation of this repair... Question.. I have a 01 explorer 4.o sohc and I am getting a jumping tach needle. I can not find anyone who has a answer for it.. it will sit at idle then start bouncing around... Any clues?
If my 1998 Explorer sits up for a few days when i need to repair it, I'll start it and get a strong exhaust smell coming out of the front of the engine that kind of dies down after a few days, but not all the way, and before it sits up I smell burning metal from the front !!
I just subscribed I have a 1998 ford ranger 4.0 liter v6 xlt 4x4 I got the p0171 p0174 codes could I have the same problem as in this video I have rough idle
Great Video I have a 2000 Ford ranger 4.0 with it showing a P0171 lean condition bank one Check Lite... once every 300 or 600 miles .. The truck is running good... only one time it would not idle . Could it be a Fuel Pump going bad? Over all the truck is running great .
gotta 98 ranger 4.0 been babied and is mint 100k miles, I just started getting 171 174, checked pcv valve hose fine, I smoke tested , sprayed brake clean, and tried propane when cold and warm and no change to engine speed but short and long trim stay in 25% range when I take it and and give it gas long term dives to zero. Fuel pressure 65psi, new fuel filter I dont want to change intake gaskets Unless I have sure reason to. Or is that the only option for vacuum leak in this engine, Maf reads fine, and so do O2 sensors, no exhaust leaks, what would you try next.Your the best on the net!
Hi. I have a 2000 Mercury mountianeer 4.0 soho engine. I have a pretty rough idle. No DTCs. Fuel trims are ok, long term is adding a little more than normal. I checked my pcv and it's not leaking. My PCv is in a different location than this video though. Any thing common with these? Sort of hunts. Only rough at idle. Minor contribution hits on most cylinders.
I thot some of the readers might want to know, if you happen to accidentally switch plug wires 5 and 6, you will get a P0174, high long and short term fuel trim bank2 only, and loss of power, but no check engine light, and no backfires, runs only a little rough,, ask me how I know :) the correct cylinders are noted on top of the coil , very faint on this vehicle but i was able to find them
I have a 2008 ford ranger 4.0. , I'm replacing spark plugs with motorcraft plugs that originally were in. Is it recommended to provide anti seize compound on the plugs , if so what brand ?
I just did a top end job on my '99 Explorer 4.0L SOHC (heads replaced, every gasket and o-ring, timing cassettes, tensioners, chains and sprockets, etc.) and now my brake booster is leaking vacuum. It's running rough at idle, but no codes. Whenever I disconnect the line running to the booster and put my finger over it, the engine continues to run rough. I did have 90 psi compression on #1 cylinder, but I believe it was a stuck ring. Compression is now around 150+, so I know it isn't that. I haven't checked the PCV yet, so I'm going to give that a shot next. Any tips on what else can be causing that?
So I just got my check engine light for these codes on last night. And this morning I was looking around my engine and I realized the part that you showed me that had the hole in it was actually just disconnected from the tube so I reconnected it but my engine light still on?
Hi I have a 1991 Ford Explorer 2 door sport and on the valve cover there is a sticker showing the engin code number, unfortunately the sticker is very badly worn and I cannot find the engine number anywhere. Is it possible its stamped on the engine block somewhere, many tks ,,
When I startup my 1995 ford explorer it over idles like it idles almost to 2000 rpms and then it would go down and when I drive it over idles to what could be the problem?
I have a Ford explorer xlt 2006. Had the gas filter changed then the service engine soon light came on. I took it to the shop and it was showing codes p0190 and p0191. The mechanic told me it was the FRP sensor so we changed it but the light came on again and the car started to have some issues only when firing it up. it started to lose revs and shake a bit before it reaches the 750rpms It's not all the time but now I hear people telling me it is the gas pump and that is expensive. I don't really understand how on earth after changing a clogged filter the truck had no lights on and with the new it does. I need some help
My fiance 99 exsplorer 4.0 has been fixed twice and still runs rough so any suggestions if I check the tube and it's not that. I've worked on cars years ago but not these often. I'll check the line soon and hope it's this since she's paid the guy over 300 already once a tune up and today 200
Thank you Brian, With 2003 Sport Trac V6 4.0L what must I do to re-tune or adapt for flex-fuel...?? By "flex fuel" I mean using any combination of Gasoline, E10, E15, E30, E50, E85, or pure straight ethanol....{in a just pump and go fashion}. Since or local stations now put in random amount of ethanol I never really know what I am running.. E85 might be E50 .. Pure Gasoline does not really exist at most stations in Missouri {due to government mandate to add ethanol/alcohol}.
I've a,94 explorer xlt.4.0 I'm having issues with my rpms going up. Then down. It's starts very good. I've been told the power brake booster could be the culprit but darn like you said. All these parts can't just go out I'm not ready to sink much more.. Any suggestions
laschell59 If you truly have a large vac leak like I think you do then you can just take off each vac line and plug the port to see if the problem goes away.
Hey! Good evening. I have a 2002 explorer 4.0 with a new engine with no more than 4K miles on it and my rear timing chain has a bit of a noise, I’m wondering if I can get away with replacing that external tensioner. Not sure why my new engine would have any noises at such low miles.
I have a 1999 ford explorer sport, does its spudders when you make a complete stop it will spudder here and there like it wants to turn of but doesn't the idle barely moves when it spudders , put it in park a leave it for a while like a minute and it tuns off byitself?
need your help. what is the piece called. on a 2004 Ford explorer. not the radiator but behind it. there are 2 hoses that connect to it. right above the drain plug of radiator. It's the one right behind the radiator, thank you.
I have the exact size motor in my Explorer, but its 2000 model. My oil pressure gauge is going haywire and there is some ticking in the motor. I love my truck. So I parked it. Do I need to just replace it..or is there a not too expensive resolution...??
Hi I have 2006 Mercury Mountaineer, recently I am facing a problem with shifting of gears, loose /free shifting, and not engaging to the selected gear, some times gets engaged after a minute. Power train malfunction indicator shown in instrument cluster. could you suggest the real cause of this issue and how we can tackle it. thanks in advance.
I have a 2008 Mercury Mountaineer and I just replaced the thermostat housing and the intake manifold gaskets. Now that it is all back together it I am having a very rough idle/misfire. I took the intake back off to investigate and there is now oil in my intake at one of my cylinders. Could this oil be caused by a manifold leak, which would be causing the misfire/very rough idle? Tricks on getting the intake manifold to seat well? thank you
hi you helped me out before i have an used 2005 ford 500 limited and never changed the wipers before one was have gone went to change the wipers at advance auto and the guy told me he aint never seen a nut on each one to hold it on and said i might have to replace the wiper arm and i want to know do i have to changed the wiper arms to get the right end pieces to lock the wiper blades in instead if the silver nut please help have pictures and don't know how to post pictures on here
It seems the arm has been botched yes, all wipers clip into the arms no nuts or bolts required. I would change the arms out and some new blades and you will be all set with the correct arms and tension so you have good clearing of the windshield for the upcoming fall rainy season and winter snow.
Hey man I have this issue but I have the sohc 98 Ford Explorer 4.0l but my motor don't look like this one any clue were it is on mine because I have same codes and everything u are saying is what my truck is doing
