The car is an 89 HF with a 91 Si motor. Everything works fine except for a very bad misfire. It has a brand new distributor from distributor king, so I doubt that has anything to do with it. I'm still running the original pm8 ecu because the pm6 I have won't turn on the fuel pump The plugs are close to being fouled and its spitting raw fuel out the tailpipe, that's how bad it is. I can hook a timing gun up to any plug wire, anywhere on the wire, and the light flashes very erradicly. I tried the gun on my truck and its fine, so the gun is good. Anyone have some suggestions?
