Fords will shut off the injector once it sets the code, so there should not be any adverse affects.
No, does not.
Have had a bad COP, never set any lights, no codes just a low speed miss. Idled perfect but give it a bit of throttle and the miss would start and get worse up to about 45 MPH then even out a bit up to 55.
Only way I found out was to take to the Ford dealer, pay the diagnostic fees and with their OBD2 computer it gave the percentage of power imbalance between cylinders.
On another truck the dealer failed to properly torq the plugs and had a miss and raw fuel smell in the exhaust.. No codes and no light..
I retorqed the plugs, no more raw fuel smell in the exhaust.. BUT, after a few thousand miles I started getting codes set for one of the OXY sensors..
The raw fuel dumped, poisoned the OXY sensors..
