I have a 2003 dodge dually with a issue i have never run across with my second generation dually.. as of yesterday, i can crank it up put in drive or reverse it will not accelerate buy the pedal ,when i put in back in neutral it revs up and then returns to an idle... i can put it back in drive and let it idle till it picks up some speed and after it shifts from 1st to 2nd then i can press the pedal and it will then accelerate with no problems ... no codes , no check engine light , disconnected battery , and still nothing.. I am at a loss.... anyone experienced this problem or can tell me what to look for????????? thanks.... just a note for help on this i can put in drive and let it idle till it reaches about 15 mph then i can feather the pedal and it will finally start going and shift and reach cruising speed. its just on initial take off that it will not accelerate by the pedal..... thanks to all the people that have read this but i would really hope that some-one can help with the problem
