Hmm, I used to think it was either buyer's remorse or lemon worry, but I used to hear something coming from my engine. Sounded like it was running rough, but when I turn down the radio () I wouldn't hear it.

Nice to know it's probably just the valvetrain. :D

Take it to the dealer, if they give you the run around or "cant duplicate the problem" take it to another shop and have them write up their analysis, then take it back to the dealer. I dont think anyone here would be able to determine what the problem may be without looking at it or hearing it.
