How can tell if the ECM is going bad?
 
My car has started to act strange. I installed the PL card and every since then it has a miss throughout the rpm range. Touch the card and it will almost die and then rev up to around 3k. I got it to not skip a couple of times by pulling the card out some. Well now I can take the card all the way out and it still has that miss. No codes or anything and the case of teh ECM was hot to the touch.

I just do not want to drop the $$$ on another ECM if that is not the problem.

I know it has to have something to do with the ECm as I got it to not miss a couple of times... I guess I am just looking for some re-asurance. Does this sound like something the ECM would/could do?

Car has the TT chip in it and ran real good until this..

That is a pretty strong indication of an electrical problem.

Try to get one from a junkyard and swap it in. It does sound like a damaged ECM from your description.

Thanks. I can always count on some help from this site...

What cars beside the turbobuick had these ECM'S? I know I have to swap both chips out but I am lost on what vehicles to look in beside a turbo regal..

Thanks for the information. I can get one from the dealer for $82 but wanted to buy a good used one for cheap to make sure that is the problem.

the old gm trick to seeing if computer is bad... bang on it while its running see wat happens if it dies out its probably ecm. grab wiring harness and wiggle it around see if there is a loose wire maybe
