Ignition control modual possesed?
My sister in law has a 92 Ch**y Cavaler 2.2 four cylinder that dies every time you romp on the gas for passing gear. You're doing 40, floor it , passing gear kicks in- followed by the check engine light and then it dies. let it set for 10 minutes and it will start again. I put in new plugs and plug wires today and took both coil packs into Autozone and had them tested -both came out fine. Whatdo you all think? Ignition control modual or some other sensor?Thanks in advace for the help!

Check codes; there will be one if the check engine light is on. There is a way to read them with the check engine light just like the older Fords. I found one site on how to read them:

Might have to do some searching for a list of codes.

Thanks for the help! that's really good to know about the trouble codes! I was reading up some more on it last night and found out that when the car is cold and you first start it, the computer is in an "open loop" using pre-programed settings for all the sensors. once you drive for a little bit it switches to a closed loop where the module takes readings from all of the cars actual sensors. so I'm leaning towards there being a bad sensor / bad connection on a sensor now. The crank position sensor was all oiled and greasy should have cleaned that up while I was under there, I'll have to do that when I go back to apply some dialectic grease between the module and coil packs. Would have been too easy to have done that while I was there!

I have found a lot of odd behavior from GM cars. My favorite is if you have the car floored going up a hill, and flash the high beams, they either stumble and chug for a few seconds, or if you let off the gas just as they stumble, they die.

<!--POLLS--><!--FILES--><!--SIGNATURE-->Wow! I must have been REALLY tired when Iwrote that last post ! It read like Mel Tillis trying to speak Ebonics. Sorry about that! Well anyway, I tried a new fuel filter..seemed like a good idea but that wasn't the problem...still wont start. I thought I would pull out the crankshaft position sensor and see if it looked oil soaked or corroded. Has anyone here tried to get out this sensor on a 2.2 cavalier? If it ever comes up just have someone punch you hard in the mouth instead. It will be less painful. I get to go buy a special tool tomorrow. -Foot long needle nose pliers to try to extract what's left of the sensor after it crumbled while I tried to pry it out of the block.

well, I got the old crank position sensor out and put in the new one and it still won't start.I remember now why I try to stick to only 1980 or earlier Fords...
Anyway, I still have no spark at all, I'm afraid all that's left is the ignition control module. Is there any other sensor you all can think of that would cut off spark entirely?the ICM is $135.00 kinda expensive guess...) -Thanks for any and all advice!

> all that's left is the ignition control module.
There is a reason both Ford and Chevy lost their TFI lawsuits.
One common problem with the Chevy cars from 80s to 90s is the EPROM going bad, it will cause a no spark/no start problem.
