YEP, I REPLACED THE PICK UP COIL BUT THE CEL CAME BACK ON AFTER I CLEARED THE CODES. IT DOESNT SEEM TO BE RUNNING BAD AT ALL, BUT WOULD I EVEN NOTICE IT IF IT TRULY IS JUST "RANDOM" MISFIRES? I'LL CHECK BATTERY & ALT VOLTAGE. IS THERE AN EASY WAY TO CHECK FUEL PRESSURE? i REALLY DON'T WANNA HAVE TO DO INJECTORS.

 

Whats this plenum issue zman17 was talking about?

 

Check the stickied thread at the top of this forum.

 

Clogged catalytic converter could be the issue, but since the cap, rotor, and plug wires were changed, that's where the culprit most likely lies.
