The PCM is basically the cars computer. Changing it is easy. Some may need a case learn done So far as I know, 96 is a simple swap, and 97 you change your knock module.
I called for a quote this morning and for the Delco PCM they quoted me $249.00..So I will look to do this first:
Open and remove the PCM cover, turn the cover upside down to view the
relay and fuse positions on the inside of the cover! Remove the individual relays and fuses one at a time, removeing the old
di electric grease completly with knife/metal finger nail file,
spraying the inside of the female contacts(inside the PCM Box) with electricial contact cleaner, letting contact cleaner evorporate completely!, then apply di electric grease( which can be purchased at radio shack) on each side of metal contacts before reinserting into PCM housing,pressing firm but gently for seating! If contacts aren't
seated correctly can result in intermettent elcerticial problems!!
I removed the ABS relay from the PCM case and it was covered with
blue colored powered,cleanded each individual relay and fuse of
of old debree and reseated each individually. Runs great, only cost a few hours of my time and not dollars!!!!!!!!!!!!!.
I'm sure the Bonne'* PCM box is different from this one but I will clean ends and relays first before paying $250 retail...
