so, i have replaced the dizzy cap,rotor,plug wires and plug(ngk iridium's) but i still have a misfire on #2. sometimes it hesitates or stumbles around 2k rpm. could this be a coil issue or something else? i have a CEL and all i get is misfire on #2,nothing else. i tried to replace the fuel filter and will never try that again,the worst engineering i have ever seen. i dont think the o2 sensors would cause this but i could be wrong

thanks

Misfire on No1 (P0302?) is a miss on cylinder no. 2. The issue doen't have to be electrical. It could be a faulty injector or intake manifold air leak. For ignition check for a cracked distributor rotor, distributor tower crack, bad #2 wire, bad #2 plug.

good luck

 

it was a bad ignition coil. the old coil was bad,looked original hitachi. replaced it today and everything works fine. thanks
