I was told by three different dealers that I need a new PCM. I would rather not get one from them because of the price. Anyone have a GM part number for the PCM so I can look it up somewhere online? Also, is it just "plug and play" or does it need any programming or calibration from the dealer? Thanks.

 

I found an ECM at newgmparts.com for a list of 225.00. Does this sound like it?

 

I know you have a 94, but the 93 one is, 88999183. It is $225.19. Sounds like you found it.
