I have a 2002 ram 1500 4.7L, while cruising at highway speeds the truck will jump a few hundred RPMs then go back to normal. It only does this in OD it seems like. The truck accelerates cleanly and doesn't have any stutter to it. Could this be a sign of a bad torque converter or bad throttle body sensor? Or could it be that I need to clean some grounds in the engine? Please provide some insight as I am not super knowledgeable on this aspect of a truck.
