misfire on one cylinder help
have a 91 z32 na one cylinder misfire at low rpm below 2500 after that seems fine spark plug good, coil pack good, compression good, injector new, power transistor unit good, connectors to injector and coil pack have voltage and signal, what else could it be thanks

did the power balance test, switched the coil packs around still on same cylinder, also checked the injector and don't hear any malfunction. only other thing i can think of is ecu or harness. is there any way to read coil pack signal on connector.

Stick a long screw driver to the coil pack and injector then put your ear on it with the car running, if you hear loud obvious clicking then it's working. Also what did you get on the compression test compared to the rest of the cylinders?
