Acts like a fuel delivery problem,does not show up on engine scan, could be fuel pump, idle sensor, or injectors. I have not had this verified by a certified mechanic yet.
Dodge really needs to step up and take care of the problems with this engine, bought the truck last year and the stupid never ran right form the time i got and i can't get my money back, so far I have spent more money on repairing the truck than i got it for over $7,000.00 and it's in the shop right now with the fuel injector problems... We need to get together and sue the hell out of Dodge to take care of their mistakes, anyone feel the same drop me a line here... good luck many out there like me with the same problems... DODGE SUCKS ASS
Got the truck with 38K miles on it and shortly thereafter, the RPMs started fluctuating both while idle and driving. Occasionally the check engine light will come on. Upon taking it to the dealership, I was informed this was "normal" and that the computer didn't indicate that the check engine light has ever come on. The RPMs fluctuate worse while the a/c is on, but doesn't do it as bad with it off. No one can tell me what's wrong, so I guess I'll just drive it till it dies...
Update from May 26, 2009: Good news... after literally years of my truck not running right, twice in the shop with no results, spiking RPMs and eventually erratic shifting, I changed the TPS. Cost me all of $40 and now it runs like a dream. Hopefully the same will work for others.
