okk so heres the story. me and a buddy are rebuilding a 1997 gtp engine and the only pcm we had wwas a zzp 1.0 that said gtp g code deletes (rockers) and the first time we fired it up she wasnt running right. so we took the pcm out of another 97 and made a few other adjustments to the car to make sure everything was on right and got it running. The problem is that after that we took the pcm to put back in the car it was originaly from the car wont run. it will start and stay running for about 2 seconds then die. we tried resetting things doing a security relearn everything. then we put the other pcm in just to try all the bases and it started right up. my question is what would cause the original pcm to not work in this car now, how do we fix that, and in the mean time what kind of damage could be done running a pcm with the codes for rockers deleted?? i need help!! thanks!
