Don't drive it hard w/ the MAF disconnected and stay out of boost for sure.

I don't have a link offhand to what the normal values are. I'd have to find them on here somewhere. Before I forget again, what year GTP are we dealing with?

On the coil pack with the stripped screw, is it the screw itself that is stripped or the ICM plate that it bolts to?

with the MAF out and the sensor before it, on the intake.With the MAF off and put in D gave little gas( with brake pedal down) got car up to about 2000 RPMs then starts to misfire. also when i take off the gas when doing that the RPMS get almost so low it stalled. like 400RPM.

The year is 98. Supercharged.
Also the coil the has the misfire is also the one with bolt top striped. cant get sockets or vice grips to catch to get to turn.Going to try again in the morning. not sure how but i gotta get it out to Swap with my other GTP (2000). thats how i found out the coil didnt work about three months ago.

Should I get ICM tested scanned at part store? I hear that sometimes there useless tho.
