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..

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.
