I swapped in my obd1 pcm yesterday, and 1. it idle around 700-750 (900 on obd2 pcm), 2. it would not let me put in into reverse, I had to "crash" through to get it in. I don't have my interface cable yet, and I am going to leave it stock for now, because I'm not doing anything til the summer. thanks in advanced.

 

did you change the block knock sensor as well?

 

I soldered a 2k ohm resistor inside the pcm so I could use my 96's knock sensor. It turned out to be a problem with one of the sensors, so I replaced it, and decided to sell the 95 pcm (check the for sale section) and trade my 96 for a LS1. Anyone want a obd1 pcm?
