Has anyone reset a CEL while the car is running? I have a Fabspeed exhaust and get P047F, P1317/P1318 - all related to my the Fabspeed not having valves...
I've been trying to get something from Fabspeed for months to fix this... and crickets. Although I just discovered today that the guy I had been talking to left suddenly... so...
Anyways, it's annoying to have to stop the car, turn it off, reset the CEL, then start the car again.
Can it be done while the car is running (driving) without hurting anything?
