01 379. Changed the sensor on the throttle pedal due to a dead spot in the 20-30% range. Truck ran fine for a few months then it started not coming down to an idle all the time (would stop at around high idle setting) and wouldn't let the engine brake engage when the pedal was released. Made shifting interesting a couple times.
Installed a new one again and everything seems to work fine. Except if you press the throttle pedal all the way the STOP ENGINE light comes on and it cuts power til you let off a little then it goes away. Ideas?
