Re: do i have an engine problem?
Both of mine do this; I will say that mine is better than my wife's. I have a Volant air intake and a catch can. While I don't think these are the fix all it's apparent that it's helped. Probably the catch can more than anything. Sounds like some of the new tuners that are out will help but none seem to deal with the transmission kick-down which is what you are really talking about. Mine is sometimes very sensitive and other times it's like WTF?
