RandyA Posted January 15, 2016 Report Share Posted January 15, 2016 A couple in the same CG as we are came in today with a 1998 MH with a Cummins 8.3. The entire rig is cherry with only 60K. His problem is the engine will occasionally suddenly rev to max RPM even if he is not pressing on the accelerator. It can be idling or driving down the road. Obviously a dangerous situation. He asked if I could look at it since I had a HDT. Unfortunately my knowledge of this engine is minimal. Charlie jumped in with me and we could not find a problem or make the engine repeat the problem. As expected, the accelerator is wired. The pot on the pedal feels smooth with no flat spots. The injection pump is the square one (vs. round) and of course the injection system is mechanical. The owner is hesitant to drive the rig with the problem and he is not familiar with any service facility in the Melbourne, FL area. Anyone have a clue what might be going on with this engine?
