There are a lot of enthusiasts on here who feel that if it ain't smoking like a train and rattling like a 12 valve then it ain't running right...but from what I'm reading on here it looks like I would need to do some things to an 08 just to make run right.
What's a P0154?Compared to my 99 with chip exhaust and intake this 08 is a monster!! I have never had a code thrown yet that I saw but the dealer did tell me when I took it in for a flash it had a P0154.
