2.2 EcoTec Misfire MOST COMMON FIX! 

I went to the junkyard and got the whole assembly. (Ignition Control Module, Coil Pack, Boots) all for $30. The scrapyard is filled with plenty of those cars. Fixed my issues.

THANK YOU!!! I changed mine 4 years ago and recently was exhibiting the same issues you described. I refused to believe that it was the module and after trying almost everything that you did and after watching this video I decided to swap it out and PRESTO! Dude you saved my sanity..THANK YOU!

I changed coils & plugs on my 2011 2.2 HHR ..what a Difference 😀after 100,000 miles👍

Wow. this video help me save big money.Thanks you very much sir. my 06 saturn ion fixed for $25 order from ebay.

Omg thank you soo much!! I fixed my 06 chevy cobolt because of your video. Had the same problem. And couldn't show n e 1 what was going on because it was random. U saved me a lot! Thanks 😊 🙏

DUDE! I have been searching FOREVER for this answer. THANK YOU!! 🤟

Most people don't change the spark plugs on time. This makes the Control module work harder. Over time it fails from too much heat. Buy an OEM PART such as Echlin or BWD spend the extra money it's worth it in the long run.

Thanks for the vid. Changed plugs and fuel filter first and nothing changed. Then changed the ICM and voila.....purrs like a kitten...2005 cavalier

I just bought an 03 saturn ion today (3/5/19) its a neat lil car

I had all those misfire codes on my 2002 Grand Am too. I replaced the Champion spark plugs with oem NGK's - Problem solved. Nothing wrong with them that I could see - they just weren't NGK's.

@8:30 On the back of that Ignition Control Module you need to apply a little bit of Thermal Paste to help w/heat withdrawal. I applied maybe too much, like a butter on a sandwich, but everything works fine. I replaced it just bcs of the mileage. The car is 2003 Chevy Cavalier w/2.2 L EcoTec. I didn't know that part can cause misfire, thank you for pointing out and for the great film as well.

My Ion 2.2 EcoTec SUDDENLY started misfiring last night. Thing is, you priced the ICM at 60 bucks but you can get them new cheaper online. I ordered both that and the ignition coil (which is basically the Ecotec version of spark plug wires) but because it SUDDENLY started misfiring it could be a fuel injection problem because the problem didn't get worse over time. It literally happened after I got back home from the movies (and it was running fine then, and all the months before that), went inside to get my gym bag to go work out and the problem happened then. Five minutes after it was driving fine. OBD code read P0300 which is "random misfire." I really hope it it is the ICM because I am running out of money to fix my cars.

I have a 2002 Pontiac Grand AM, and I'm having the same issues you had. On a cold start it would run fine, but after heating up then it would misfire. And if I turned it off then on again, while still hot, it would continue to misfire. I'll switch it out then get back here, thanks a ton!

Can't wait to get home And try to see if this is the issue. Thx for this helpful video. I'll report back soon as i can if that helped or not

dam u seem calm about it, was that always the case trying to figure it out..I would have blew it up

Saved me ! God bless your soul.

Get to the point my guy

This didn't fix my "Random Multiple Cylinder Misfire" issue for 3 reasons... 1. There was a recall out for my car, dealership replaced the ICM as part of the recall. 2. Mine is an 07 Ion, the ICM isn't in the same place and doesn't look like this, nor do my coil packs. 3. Engine ended up blowing a hole in itself 1 year after recalled parts were replaced. 😖😡

Going to try this, your video is the only one that matches my symptoms and makes sense.

Ignition control module could be it Thanks

OK I have a 04 chevy cavalier. I replaced the spark plugs, coil pack and the module. Also did a oil and filter change. I found oil in the hose to the intake. The car is a little rough. Should I change the pcv valve to fix the rough idle? It runs OK but it does have check engine light on

i have a 2003 saturn ion i had the same problem, i changed it just like you did after a couple of months of running fine i ran into the same problem, i found out the control module gets hot because the exhaust manifold is right there and the gasket was worn out! ,also the intake manifold made a hissing sound there were gaps between the seems of intake manifold i could fit my fingertips in . im waiting for parts to fix.

I replaced my coil pack and ICM years ago from a junk yard out of a Pontiac for $40. It fixed my problem then and its been running for 7 or 8 years perfectly. My current issue doesn't seem to be the same. The garage has had it for nearly 5 months. Wasn't misfiring at all. Some computer thing is burned out. Had I known this is my issue I would have replaced it again myself. I put in a new starter. I'll kick myself if my issue is an ICM again!

Is there any way you could just say what it is

FYI The Control Module I got (BWD) at a local parts store in southern Oregon is a sealed package and non returnable if the seal is broken around 86.99$ as of 8/13/19 coil pack 82.99, sparks plugs 7.99 x 4 = 31.96. Total cost 201.94 Car was driving fine and then I slowed to a stop for a traffic light, and when I started again engine light came on, No power and it felt like it was in limp mode.

I have an 06 Saturn ion with 297,000 miles. When mine did it, it ended up being the wiring harness that goes from the computer to the coil packs

That motor seems kind of loud compared to mine mine runs real smooth my bad I think that it is the fan running that makes it sound louder

Thanks dude! Saved me from buying a cat!

Changing the coil packs made my engine hesitation for get better for awhile… but I now am having problems again so I will replace both this time… sure didn’t last long… I think perhaps resetting the icm made it work better for awhile not sure.

I watched a video where it was recommended to do the coil pack and module together because the pack can cause the module to fail. But I guess at this point, it doesn't matter. This video was posted 5 years ago, and that Saturn is probably long gone. I have a 2003 Ion, and it only has 121,161 miles on it, and I think it might need a new timing chain. I just put $850 in it about a week ago, and I think it's time to call it a day on the Saturn.

Now can missfires cause engines to knock or even stall?

Help a lot! Thank you Sir

very good video keep up the good work.

Thank you thank you thank you!

no fuel injection or intake /throttle body cleaning?

Ok, so my 04 Pontiac Sunfire is misfiring when I first start it up. Worse in the morning after it sits all night. After it runs about a minute it smooths out and is just fine. Then when I get up to the speed limit whether it be 30, 40, 55, or 65 mph it doesn't seem to matter which, it starts to jerk like it's cutting out on me but will stop and run smooth again if I give it more gas or even let up on the accelerator. Plugs and boots and fuel filter are all new and even done an oil change just to rule out another item. I have had this problem since the end of last winter and when It was cold outside getting it started was not an easy task . Some days it would start and run fine without even the slightest miss and others it would start and miss really bad then die. I would have to keep restarting and finally after several tries it would keep going and then smooth out and be fine for the day. never found evidence of oil or any other contaminants on the plugs and plenty of fuel pressure at the rail. Have been suspecting icm for some time except for the problem being severe when cold instead of when warm or icm being hot. ******UPDATE******** Thought I would give an update on the situation with the Sunfire. If it never helps anyone who comes across the same issue then maybe it will give some entertainment. I'm still trying to solve this problem . I should've gotten rid of the car by now but I have never dealt with a car that had a problem I couldn't fix. It's now become an issue of fixing it for pure spite. I've swapped out the ICM and the PCM and no change, still the same issue except now I can start and it rough idles for a few seconds, smoothes out, then it's all good till it reaches normal operating temperature then back to the missing out when at idle or trying to maintain an even speed. So far I have replaced ,all electronics and every sensor. Even replaced intake manifold gaskets, injectors and I rings, fuel pressure regulator and gaskets, throttle body gasket, TPS, IAC, O2 sensors, all fuses and relays just to be sure, and new head gasket. And new coil packs made nothing better either. Have now spent more in parts than I paid for the car. Final step is just pull motor and compete tear down and rebuild.

Great job. Thanks

Thank you.....

What do mean by “misfire”? Wasn’t explained. Do you mean, engine skipped and clunked briefly? Or that the engine actually shut off? Thanks!

Thank you so much your video is very helpful

How do you bench test the ICM or the coils? My engine cranks but will not turn over so I can't do any run testing.

was the valves making a clapping loud noise as well?

So what was the car doing ?

I just changed my ignition control module, coil pack, spark plugs and boots and I’m still having the same issue. It did not stop my problem(the same thing you said you were having)

How do you call this part?

Thank you. I have been making this comment on our saturn ion. 2004. My husband let it sit for 6 months out of frustration because of a pass code lock couldn't start finally reset alarm fired up but the misfire code is on and I swore its the eco because it has come back again. I'm gonna try the eco fix.

What part number would that be

I have a surging problem my rpm jerks back n forth it’s on a cobalt

I wonder if this is my problem. All of the sudden my cavalier started to misfire really bad

If this is about a missfire why sooooooo much dashtime?

Sam problem I'll try and replaced

I have a 2004 saturn ion. I changed the ICM, coils, and spark plugs. It really smoothed put the misfire but now. I have a P0341 camshaft position sensor code. Which the 2.2l DOES NOT have a camshaft position sensor. I can not find the problem. Does anyone have any ideas?

In my case, PO304 problem was the egnition coil

You saved me so much money thank you

Could this cause a P0300 random misfire code?

Ok so my 2004 saturn ion has been misfiring a ton lately and i have went through and changed spark plugs fuel filter and the number 2 O2 sensor. I think it its my icm has went bad. My question is if yours was like mine and whenever you started it it would misfire a ton and after 30 or 40 minutes of driving around it would quit for a while or whenever it wasnt misfiring as soon as i brought the car to a stop it would begin misfiring. Did your car do anything similar to that

I have an 06 ion. How can we test the ICM?

Replaced mine a year ago and now it's doing it again

Thank you so much!

These engines have guaranteed issues with timing chain guides..(especially the upper guide) which leads to chain jumping a tooth and loosing timing

Thanks Guy

I have the some problem that you have

So I bought an AcDelco ICM, instead of one of the cheaper ones, and my misfire actually got worse. Before I had the P0303 misfire code, after the new part I got a P0300, so back to the drawing board.

I have a 2004 saturn ion, i am getting 3 different codes, a p0300, a p0455 and a p0422 (which I already determined was a gas cap issue and a new one is on the way), the random misfires started happening all of a sudden and the wheels are getting next to no torque. I took the spark plugs out and saw that 2 out of the four (in positions 1 and 3) had almost no iode left,. I ended up replacing the spark plugs. All that did was make the car start a lot smoother. My next move is to replace the egr and icm and hopefully that will change something. If anyone has any other ideas all help is welcome.

My 2006 chevy cobalt comes up code O3O4 misfire cyl 4. Replaced spark plugs, ignition coil pack, ignition control module, spark plugs, O2 sensor. Still misfiring

Had the same issue with my ion.

My car is doing the same thing but I turn it off for a min start it back and it's gone

Passlock leave door open with key on the on position for 15min

Engineers build new vehicles to cause problems and make them disposable , older vehicles had electronics and coil mounted to the fender or firewall to keep them cool . Like I said in other videos , these new generation tupperware cars are getting more and more less reliable and designed with a built in shelf life . I'll keep my old mechanical diesel .

Bro is sitting in the car while vid😂

Do you need to program a new ICM?

After market cats are super cheap for these 4 cylinder engines! Thats why there so great cus there durable and inexpensive to fix. I have 200k on my and no issues with the cat. Btw has anyone ran seafoam thru the intake to clean the engine and get some horses back??

these suffer from defective fuel pressure solenoids and lazy high pressure pumps

Does anyone have a ignition working control module for 2006 cobalt

Cat converters are cheap to fix it they clog. Take a long bar and knock the guts out problem solved.

Yeah thats true i just fix mine thanks

Great 👍 stuff good to know

Power loss is a sign of a catalytic converter and if ain't hardly any exhaust coming out the tail pipe, that's a good clue or at night time you can see em better cause they turn cherry red from being really hot cause the exhaust ain't flowing properly...I'm old school and I do things the old way cause I can't afford all those gadgets we have to have to troubleshoot em lol. The quick way to clog converters is the oxygen sensor cause the black sutt is what I think clogs em. I put a half a million miles on a 84 Ford 3.8 engine and everytime I changed the fluids I'd take the oxygen sensor out and clean it really good and I never ever had to change the cat on it., It always had plenty of power while putting all those miles on it and the only reason I got rid of the car, the radiator sprung a leak and I's to cheap to pay 360 bucks for a brand new radiator cause in the 90s a radiator wasn't cheap. Now they're under a hundred bucks lol...Especially for a cheap made 84 Ford LTD that was basically a Ford Fairmont... I'm not going to kick the tires on em cause that was a very very dependable car lol...

The cat was probably bad because of the constant misfire. They had to start somewhere

Changing the ignition control module is good for maintenance but it won’t get check engine light off

And the Chevrolet Cavalier 2003 and 2004 what's mine is a 2004 has that same motor

Throttle Position Sensor

Todo bien

So are you saying it was a random misfire?

Merci j ai le même problème

At 6:40 he finally gets to the point....Ignition control module! But, he does not explain how to test them or how to know if we are getting another bad one from the junkyard....

I am dealing with the same exact problem on my 05 Chevy cobalt.

Ok

Same issue, replaced, still same issue

Is my 2005 Cobalt 2.2 an ecotec engine or is the ecotec engine a different animal from my 2.2? And, was your fuel mileage going down and then go back to normal after you replaced the ICM?

Holy smokes. Should have been a 30 second video.

Bro you talk a lot !! At least talk faster bro just saying as a tip ( I'm trying to help u)!!!

I love these videos, I love how people posting help others out. But FOR THE LOVE OF GOD, GET TO THE POINT!!!!

Had to skip through 8 minutes just to hear about it being the ICM

Dude people suck they never get to the point lol

Way too much un-needed dialog
