Whats the probelm?

My girlfriend has a 2005 SRT-4, with a little under 30k miles and recently is has been "sputtering" when the boost kicks in. We really arnt too sure what it is. Her dad thinks it might be the gas right now. If any one has had a similar problem or think you know what it might be, please let us know. thanks.

Could be a multitude of things. Here's a short list of possible culptrits:

Spark plugs
Spark plug gap
Spark plug wires
Coil pack
Boost leak



What I would start with: getting some new spark plugs.

Is it only when accelerating if the idle is funky it could be throttle position sensor however plugs and wires is a good place to start. I have an 04 and had similar problems twice the first time it ended up being the wiring harness for the tps the second time it was a plug wire.
