I decided to put my stock PCM back in to try to fix the problem I have been having which can be found here: http://www.grandprixforums.net/rpms-...ing-58482.html
Well, now my car runs like sh*t. I stepped on it and it was extremely hesitant and jumpy for the first little bit. After about 5 mins it wasnt as jumpy, but it still felt like it was lacking a lot of power. When I stepped on it again it shifted to 2nd gear and I heard a loud squeak. I tried it twice and both times the squeak was loud between the 1-2 shift. I decided to drive it home and park it until I can figure out whats wrong.
It wasnt hesitant and I never heard that squeak with the overkill PCM in.
Any ideas?
