Resetting the ECU will only clear any learned values for idling, fuel trims/adaptions etc.
likewise.would of thought that if 2 cylinders aren't firing then it must be either wiring from ecu or the coil driver inside the ecu itself.nothing else at all it could be esp when coil,leads and plugs have been replaced.very odd
