Engine hesitation by 357magnum

I own a 2006 Dodge Magnum with a 2.7 liter engine. At times it seems to hesitate accelrating from a stop and also while driving. It seems to go away after it has had time to warm up.
My first thought was one or more bad spark plugs. It has 132,000 km's on it.
Any help would be appreciated.
Thanks in advance

I have the same problem on my 2006 R/T. I have 50,000 miles on it and it is currently in service for this. (8 months ago the dealership told me it was a gunked up throttle body and cleaned it out. I now have the car with my local mechanic who told me the charcoal canister was full of fuel (actually has caused the car to stall immediately after fueling) and is exploring what he thinks is transmission problems. We'll see what the diagnosis is.

Hi Mike,
I got my car back today. My mechanic checked the "computer library" for manufacturer's calibration updates and or corrections. He installed the latest revised calibration ID and cleared the system of all trouble codes and reset the learning adapts. He explained to me that it was much like downloading the latest updates from Windows for my computer. I have only driven the car around town as yet but I do notice it shifting more smoothly and no hesitation. Truth will be told the next time I take it on the highway for a trip. Evidently the vapor canister was a real problem and was replaced as well as the hoses that had been contaminated by holding fuel. Good luck with your car - I love these vehicles and am not ready to part with it yet. My dealer addressed none of this when I took it in 8 months ago with the same problem.
Best, Jay

Thanks once again Jay. I'll be keeping this info for future reference. For some reason the problem seems to have disappered.
Sorry for the delay in getting back to you.

The saga continues. The day after getting the car back I filled with fuel. At the first stop the car stalled and did so at three consecutive stops. I immediately got my mechanic on the phone - explained the problem and had the car stall while he was on the phone. He said there was a valve attached to the gas tank (fill valve) that he did not look at or replace because it means replacing the gas tank. This is what we did. Evidently the fill valve was malfunctioning and allowing the tank to be overfilled thus sending raw fuel to the charcoal canister which was replaced last week. The car had some significant hesitations on the way back to the mechanic as though the transmission was not sure which gear to be in. The confounding variable is the raw fuel/stalling problem which we're hoping was the case. Another expensive trip to the mechanic. I now have the car back after he tested it with filling the tank - no problem so far. I'll let you know.
Regards,
      Jay

Sorry to hear that Jay. I hope this solves the problem once and for all.
I was driving in a heavy rain yesterday and my Magnum stalled twice in the city traffic. Once I moved to the highway it was fine. Not sure what happened there. This car is causing me to worry more and more. It seems to be touchy.
Guess I'll just look for the next issue with it that comes around. (LOL)
