NO.

They CAN be remanufactured/rebuilt or NOT. Just go to the wrecker with that list. They'll know what you need.

That list is a cut/paste from GMPD.

I don't recall this topic pointing at a bad PCM with any kind of definitive proof. Don't be dissapointed if it doesn't solve your problem. This is somewhat of a 'shot in the dark' at best.

Exactly. While I like to joke about the 94/95 pcms since I've had and seen many. It'* always a rule everything else possible out of the equation first.

Don will be the first to sing the lovely praises of a pcm going bad..lol

I just bought a reman one from Kragens for $99. so I would imagine $20-40 at the junk yard.

I would try to jump the fuel pump first before you buy a computer.

PS: did you ever try the extra ICM you have? I would try that first.

With the things Franks car was doing the PCM ended up being a no brainier... He had too Many issues all at one given time to be related to any other part of the control system.. Once I saw that his car showed 181F but was still in closed loop I knew there was an issue.. That and the series Of Ghost codes...

I agree when the situation warrants, make sure you check everything.. If you can hold off on spending more $$$ untill you get the tool, you may help yourself...

And why will the ICM from the 97 SSEi not fit the car? Is the issue in the connector?

Being that I have a 95 and have had PCM issues in the past and am having a couple of ghost issues now... I really don't care for the 94-95 PCM'*...

Last PCM has been a good one tho.. Low mileage unit...

I would like to see if the PCM has any codes stored that you will be able to relay back to us once you have the Actron..... That may help us point you in the right direction..

The PCM replacement is a shot in the dark.. But if thats what you want to do I sure won't stop you from having a Spare PCM

I did same thing and it didn't fix problem. Problem was bad grounds. After that my crank and cam sensors went but after that it'* been running great! I wish I had found this forum sooner as it would have saved me some major cash!

Has 88bonne cleaned all grounds?

I think he posted that the Grounds were pristine.. Someone correct me if I am wrong on that one..

Not sure what he is going to come across.. It has to be a simple problem.. The question tho is what is the problem.. Sometimes finding the problem can be a little bit of a nightmare
