Is it possible for the ICM to overheat after say running for 10-15 minutes and cause the car run crappy?

 

Yes.

You could try shoebox's ICM cooling mod on his website, or just buy a new one.

 

Alright, I'll probably grab a new one and do the mod.

 

Crappy like? Because I suspected mine for a while... I mean what exactly would it cause?

-Dustin-

 

Missing and sputtering, from what I hear, mine hasn't gone out on me yet- or at least I think not- my car seems to be missing a little. But then again that could just be something else out of the hundred or so things that cause LT1s to miss...

 

I'm guessing the reason I'm assuming ICM is because I'm getting codes 41 and 42 (after it's been running for awhile).
