I've been having issues with my 98 gtp. Mods in signature. Recent parts replaced
- icm
- plugs autolight 606s
- coils
- tps
- flexplate
All installed by me and my friend. The flex was a pita..
Anyways, it started having issues about a year ago, high idle then stalling. I have to 2 foot it everywhere I got to keep it running. I had misfires on 1(52k misfires), 4(32k) 5(400) 3(about 200) and 6 and 2 were minimal 1 or 2. so I replaced the coils, plugs and wires. Still continuing to mis I changed the icm. Still no result. Compression is good. 134-150psi cold check. Sometimes the tach would drop from 2500 to 0 and pop back up like a terrible mis and re-fire. I unplugged the maf and it stopped recording any misfires and ran a tad better but today not so much. Back to the usual spurratic tach and yet no recorded misfires. Any help or suggestions would be really awesome!
