any clue what else it could be? I'd be shocked if it was carbon buildup, as I only have 35k on my 335 and have been running meth for almost 15k of that.. the only code being thrown is 29CF. no HPFP/LPFP related codes so I'm not sure where to go from here... I'll bring the car in next week but any advice would be helpful in the meantime!
thanks
