Well I've finally getting amanda's car running great. I have a smooth idle at about 1000rpm and no detonation (that can be heard anyway). First to fill in anybody about the 2 telephone poles in front of my house. I have 2 poles at my house, I dead stop at a pole, run past the first and get a MPH at the second. My 93 lightning runs 62MPH everytime at the poles and runs 9.72 in the 1/8th. Anyway.... When I first put her car back together I had a bad vac leak. It showed 14-15 in hg at an irratic 1200RPM idle. But the car was really strong and I could easily make a 68-69MPH run. I outran a lightly modded GT that night. The next morning I found/fixed the vacuum leak and then it showed 16-17in hg. and the smooth idle, but developed an exhaust leak from the turbo elbow to the DP. I haven't made a 60MPH+ runs since. I tried running it with the vacuum leak again and it ran the same.Its been a long time since I checked but a while ago the base timing was set at 10* and runs 17PSI. IT just doesn't feel like it pulls much at all in 3rd and 4th now? I noticed on a video from tonight when I revved it up in nuetral the engine pinged a little, but I couldn't hear it when it happened. Does anyone have any ideas at all? I'm pretty confused on this one. I change the plugs and the ones that came out of it looked great.
