I have had some issues getting these trucks to follow my idle requests.

The one I am on now is 2011 and when it is warm it will idle at 800rpm and walk itself around a parking lot at about 8mph or higher. If you are trying to stop then it can be hard on the brakes.

Other than Possibly A/C running (HVAC on Auto at 72* when it is 30* outside), or idling higher for EGT temps for upcoming Regen, I am out of ideas.

Also I am wondering if anyone knows if EGT1_A PID is the turbo outlet Sensor or EGT Sensor after the Indirect (9TH) Injector.

Thanks guys.
