Got a P0275 code so I put a new injector in #5. With AE I can buzz all the injectors successfully but am still getting the P0275 Cylinder 5 Injector Circuit Contribution/Balance Fault when running it. It's got a miss in her so something is still going on. What are the odds of getting a bad injector from Ford and if it were bad..... would I still be able to buzz it ?
And would I be able to buzz it and it not be able to function if the harness had a bad spot/chafing in it somewhere ?
