Dragracer,
My '96 did the same thing and all it was were the $45 resistor ends that go on top og the plugs. That is what regulates the whole secondary ignition systems ohm load. They are N o t o r i o u s for going bad. Alot of shops change them every time plugs are done to keep a comeback situation from happening. It fixed my erratic driveability problem. Try that instead of fearing a possible, useless $1,400 harness fix. The first dealer that 'worked' on my car threw a new MAF at if and raped me for $600.00. It Didnt even fix it and they didnt refund me. F-EM. I went to an indie shop & he knew right away it was the tips. Dealers are cool, just get the right mechanic
