have 01 24valve dodge i start it idles fine sometimes when driving it wants to take of bye its self then sometime give it gas nuthin pedal push to floor still idles what the hell

 

My first and best wild-*** guess would be the throttle position sensor (TPS). Really easy to test, so you don't have to throw any money at this problem to rule it in or out. If I remember right, when I last tested mine I just hooked up the two leads from a multimeter set to "Ohms" to the two terminals on the TPS and just looked for a nice steady rise and fall in resistance. To me, that's the most logical thing it could be. Can't think of anything else that would make your engine accelerate on its own (this is a Dodge, right, and not a Toyota?), AND also not accelerate at all when you step on the gas pedal.

 

Post your thread in the Cummins section and do a search there, you might find a thread with the same issue.

 

yes thats true ill check that out if not that what do u think but likie i drove most of the day today nuthin happen what make me think its a eletric problem

 

First, as zman said, you should post your question in the diesel forum.

And yes, it does sound like an electrical problem; specifically, the throttle position sensor. That would be the very first thing I'd check. It's not technically called a TPS in the diesels, but I think it does pretty much the same thing; tells the engine management system what your right foot is doing.
