Have a misfire on cylinder 6. Put in new plugs, swapped coils between 5 and 6, still had misfire on 6. Changed injectors between 5 and 6, misfire went to 5, cleaned the injector then it went back to 6. Cleaned the injector again and drained the fuel rail this time. Still misfire on 6. Possibly could be the connector.
Is the injection system sequential or batch firing? With batch I can swap the connectors between 5 and 6 to check. I am not sure that would work in sequential injection.
Thanks.
