I HAVE a 1996 infiniti i30 i put a new spark plug a new coil pack and did a compression test and its still misfireing. what do i do now.
check lead from coil to spark plug.
Swap the parts (spark plug, coil pack, plug boot) with another cylinder. If the miss moves with the parts one of them is bad. If you still have a miss on #1 you could try moving the fuel injector as it may be bad. If it is not the fuel injector, you need to run a compression test.
