Have you tried a hard reset on the ECM? Normally they change the settings automatically but maybe yours thinks the change is too drastic. If that doesn't do the trick then I would have it scanned using a "live data" scanner that way they can see if a sensor is out of specs but not far enough for the ECM to set a fault code for it.

Best Answer

Is the ECM in my ECU ? And where would I get or have the " live data " ran?

ECM,ECU, CPU, IPCU all do the same thing just different letters depending on what the engineers decided on calling it, as far as shops all you have to do is just call them as ask if they can do "live data" scanning.

Ok thank you I will give it a try

What if I flash my ecu ? I'm about to do a sct flash would that fix the problem too? Or do I have to get the live scan b4
