after i replaced my head gaskets all 8 plugs are arcing on the heads..i changed almost everyground except for the one that comes from the solenoid to some where under the motor..car runs crappy as hell..but the weird thing is that last week i drove it how it is and all of a sudden it started running perfectly fine for about 2 days but then suddenly went back to crappy..wat can it be..it has autolites 3924's gapped at .032
that one last ground is bad?
bad solenoid?
bad computer? any suggestions would be greatly appreciated
