Re: misfire on cylinder 4 with AEM, 1990 DSM coilpack setup
Have you tried swapping plug wires around? Sounds like a short in that wire. The transistor generally affects both coils and you get no spark. And if one coil was bad, it would affect 1 and 4, and it would not fire when laying on the turbo.
