I had a bad coil pack harness. The wires were old and brittle after being exposed to years of heat. I got a new harness and everything ran sooooo much better.

just an idea for you.

ok. Disconnect the battery. unplug the ecu. Now shoot from the ecu plug to the igniter plug. for ohms with a multimeter. If it is a good wire you should see between 1.0ohms or lower depending on what ground your using. Follow your ecu pin out and get back to us! shoot all 6 of them. Need more help let us know!
