help...two cylinders seem to not work...
Saturday, January 06, 2007 10:53 PM
I was wondering if anyone has had the same problem as me with the ecotec 2.2 and the hahn stage 2 kit. about two weeks ago, i turned my car on and it sounded all messed up and it smelled like gas. it sounded like one or two of the cylinders were passing cold gasoline straight through. Since i needed an oil change anyway and i get them free at my dealership, i asked them to look at it. they said that it was a broken ignition module,
so they got a new one to help me out.....A.K.A. about 300 dollars.... it ran fine for about two days and tonight it got all messed up again... same exact symptoms.....i think it's the coils....but i have no idea....What should i do? i'm pissed.....

check the plugs (condition, gap), check the injectors, compression test, leak down test, pull the head and look at everything...

in that order

might be bad plugs, injectors, bad pistons(cracked), ringlands, head, a million things

what was your boost range? built or stock long block? normal a/f ratio? iats? egts? how long were you turboed?

Damn...well stock internals, 6-8 psi... running rich all the time, about five minths turboed, srt-4 plugs, got messed up when it was really cold outside and it didn't want to start......initial diagnostic says blown coil drivers and misfire on cylinders 1 and 2. What should the gap be? they are four tip plugs, so they should be fine...

I also have a Hahn stage 2 and similar problems. I have had a misfire only in cylinder 3 and have tried everything and can't seem to nail the problem. When you have a coil problem, I believe it should always be two cylinders misfiring since each coil fires two cylinders in our older Ecos. It has driven me nuts and I can never figure it out. I always get a misfire in cylinder 3 code as well as a "bank too rich" code with my CEL. I am sooooo tired of it!! Best thing to do is follow what Acer said and just systematically check each thing until you find the problem or go insane!

The SRT4 plugs are the right ones for the Eco. Learn before you advise.

Are you using Bosch +4 plugs? If so there's one problem right there.

Ignore the bank too rich code. It's a side effect of the 36# injectors on a ECU tune meant for 24# injectors. You can get rid of it by investing in HPT though.

Ryne - the tech guy at Hahn told me I shouldn't ever get any codes with the Stage 2. I also have an 02 Eco, I'm not sure if that matters. He had told me I will not ever see a CEL if tuned correctly.

Well he was wrong. I've told Bill about the code. I have the Stage 4 kit now so I think I know a little about the kit and it's issues. LOL.

Thanks for all the advice....They are bosch +4 spark plugs....what's wrong with that? What should i have instead? well i'll start breaking it all down tomorrow....the other problem i have is that the fmu is turned all the way down and i'm still running really rich...any way to fix that? well i just hate the way the engine keeps messing up...What's the next thing that will break, i might as well try to replace it before it blows.....hey and how much are you pushing out at stage 4?

Bosch +4 plugs are the @!#$tiest plugs you could ever buy. If your putting a plug made by Bosch into your motor your only hurting yourself. NGK Eco or SRT4 plugs, Champion SRT4 plugs, or AC Delco Eco plugs are the only ones you should EVER be using.

As for my motor....it's set up to make 400+WHP @ 20PSI. Don't have any exact numbers yet though.

Sounds like you have a bad cam sensor, most OBDII computers will still run with a bad cam sensor but only in default off the crank sensor which means it will only hit on 1 and 3.

First off, get a wideband. When you say "it's running rich", you most likely look at a narrowband gauge witch is not accurate. Second, change your plugs like Ryne said. Third, check the 02 sensor to be sure it's working fine. I've seen Narrowband gauges burn 02 sensors and make the car run richer than it could take.


cps will make the car run in batch fire witch mean it will still fire all 4 but together. 1-3 and 2-4.

The Ecotec doesn't have a Camshaft Position Sensor. Thanks for playing though. I'll tell you what I told justinhc....learn before you advise.

i had the same problem. im thinking its the bosch plugs...... i dont have the +4 but i have regular bosch platinum's any way her is what i was told to do

Quote:

Get a new ICM.(sorry) get yourself a new set of spark plugs.

Check the ground on the ICM make sure its nice and clean.

Follow the ignition circuits 406 (IC Control for 2/3 Coil, orange wire) and 423 (IC Control for 1/4 Coil, white wire) for a short to ground.(chafed harness) this may occur on the AC lines near the AC compressor, on the transmission mount, or on the transmission lines(auto only obviously) where they enter the transmission. If nothing is wrong, install the new ICM, and new spark plugs.

Lets see" You mounted on the L61 head and because the LSJ exhaust was to long to mount the cam sensor you just..what? left it off! LOL! Good luck then! You'll go far with your wonderfull attitude!

WTF are you smoking dude? Where did anyone here put a L61 head on a LSJ motor? I think you and QBE have been smoking too much of the same bad batch of weed. He has a L61 motor with a L61 head genius. He even said IN HIS FIRST POST IT WAS A 2.2L ECOTEC.
