Well, I'm going to try getting another PCM. From what I've read, They are not available new anymore. Makes sense since it's 20 yrs old. I've also read that most rebuilt units fail prematurely because they are not really rebuilt at all. They will fix whatever is not working and call it rebuilt while leaving every other part of the decades old unit alone.
I found a company called A1 Cardone through Summit racing who claims to completely rebuild all units. They charge almost $200 plus a $100 core charge.
I also found them from Standard Motor parts through Rock Auto for just under $150 with a $125 core charge. I can't find any info from Standard on whether they completely rebuild units or not, but I would imagine a well known company like that would.
Does anyone have any experience with PCM's from either company? Naturally I would like to use Standard because they are cheaper, but if A1 Cardone is better, I don't mind spending a little more.
Any info on personal experiences with changing PCM's like tips, cost, or where to purchase, will be greatly appreciated... thanks, and thank you to all who helped me out on this!
