I've got a similar problem, start up and it runs like it isn't hitting all the cylinders, then evens out after a minute or two running. Thing is, I have a whistle when I first take off, and I know that it was originally due to the air horn gasket splitting. I think it perpetuates the sound due to the lack of said gasket, though I'm begging to wonder if I don't have an intake gasket leak or an injector that is sticking partially open. I haven't pulled spark plugs yet to see if I have one running rich or not.
I put some fuel injector cleaner in today ( first time I've put any in since owning the truck ), so I'm hoping to see an improvement. Probably won't, but it certainly won't hurt any.
Seems though that the sputtering problem gets worse when it gets cold out ( low 30's )

Nancy, have you tried another dealer? I was having problems with my truck with the steering and i took it to a dealer here where i live and they charged me $135 for labor and poked around underneath the truck and said nothing was wrong. I took my truck to a private shop and they found the alignment was way off despite the dealer having said it was fine!
anyways, on a different note, i kind of had a similar situation with my 02 dakota 3.9 liter. when i started it the truck never seemed to fire up real crisp like but always more like it was flooded out or something, then it would clear up and be ok. Turned out that my TPS sensor wasn't tight enough from the last time i adjusted it, i did the mod so that makes it adjustable. you can't make them too tight though or they will stick. My point is that not once did it ever throw a code. If the dealer puts a scanner on any truck and it doesn't show a code in their opinion there's nothing wrong, next customer please!!! I'm not saying that this is even the problem, i'm just saying it helped me. Have you checked the voltage on your TPS sensor? Another thing i also used to do before i discovered that was i would disconnect all the sensors (TPS, IAC, MAP, IAT) and then disconnect battery and hold key on for about a minute. then i would reconnect all sensors, reconnect battery and start 3 times. it always seemed to help.

Yeah we finally got the problema resolved. At the end of august I needed my crank sensor replaced. Turns out that sensor was bad. Took it back to my mechanic and he replaced it. No problems since. On another note, I to have that "whistle" that was talked about above. Doesn't do it all the time though. That's been happening for a while.

yeah, i have it too. mostly noticeable when really cold out. it kinda sounds like a vacuum leak to me but it's not. I learned to live with it
How did they conclude that you needed a new crankshaft positioning sensor? How much did it cost? I'm afraid eventually i'm going to have to start replacing some of my sensors. currently i'm having a problem with the idle not wanting to come down when i shift to the next gear so the truck bucks when i let the clutch out when i get to the next gear. after it's really warm it will go away. I've already replace the IAC sensor, dropped it while cleaning it!

The problem was finally identified when the scanner identified problem as Cam/crank sensor. So mechanic pulled up both readings on crank and cam. Cam's numbers were nice and even. Crank was showing alot of fluctuating in numbers both up and down. replaced crank sensor and everythings great so far. even 19 degree weather.

Just curious where the crank position sensor is located and if there is a way to check them without taking to a shop?
thanks

Yes, you can check a crank sensor to a degree if you have a multimeter, but you won't be able to necessarily get a good result simply because it can be affected by the ambient temperature and/or the engine temps. It may bench test just fine, but if it gets heated up to running temp, then it may not.
