ECM / PCM 83-1 Error Code,,,Ideas ?
2009 Fit, 110,000 miles. Occasional stalling or trouble starting.
Just replaced ignition coils & plugs.
83-1 ECM / PCM Relation Malfunction
P 0303 Cyl 3 Misfire
Do I need to spend $1000 for a new ECM ?!?!
Thoughts ?

I’ve recently had two ecu failures due to faulty fuel injectors that short out and cause a misfire as well as fry the Ecu, with the injector clips all off the Injectors and the ignition In the on position the voltage from power to ground at the injector clip should be 7.4v injectors should read approximately 10ohms of resistance. If you have any more or less than 7.4v at the injector clip the ecu has failed and will need to be repaired, I’m working on a fix right now.
