I don't have much experience with the 24 valves, a friend just bought this truck and every once in a while it will just fall to idle, you can press the accelerator to the floor, let off and it will go again. Might not do it again that day or might do it again in the next block. Throttle position sensor? Any way to repair or clean it?

 

search for "dead pedal" more info than you can read.
to start you off you will need to verify your fuel pressure and pull codes.

an apps will set a code if faulty, from dodge it can range from 400-800$ if you end up needing one do a serch for "Timbo" he has a replacement version for 160$ that is far superior to the OEM.

a 0216 code is a failing VP which means it cannot achieve desired timing, or its basically wore out, and typically this is because the lift pump is not working or has extremely low fuel pressure

here is an apps/TPS thread (all you need to know)

Thanks, I'll forward this info to my friend and maybe he can take care of it.

 

Mine did the same thing, it was the tps. Bought one from cummins for around $180.
