I have a 06 **** with about 1300 miles. Over the last 100 mile or so i have noticed a "stuttering" on mild acceleration, as if it is misfiring. No noise, just lack of power. Thought it was the gas, no difference with brand change. 92-93 octane
Took to dealer - no fault codes found, reprogramed the DME ? - will pick up tomorrow to see if better
Search these posts, and it seems this sounds like a coil issue, but at such a young age?

Coils can be old, young, medium aged .... and still be bad... but I'd also check the Fuel Pump and/or the sensor.. newer cars have the modified coils (or so I thought)... cue ltc...............

lic265 - Try a bottle of Techron System Cleaner. It's not going to hurt anything and it might cure your problem. You will know if it works before you burn a tank of gas. If it clears up, start using Chevron all the time.

Glad to be a new member of the "Coils Club" - but only after they changed out my spark plugs did my problem start.
So - Tuesday we see what happens...

Put a bottle of Techron in the tank - no better
Still feeling like it is misfiring or "stuttering " under mild- moderate acceleration
Any ideas before i go back to the dealer?
