I have a rough idle, and some hesitation on accleration. Im new to a BMW, so i cant quite nail it down. Did a complete tune-up, the works, but no difference. I was reading up on my model, but they dont have many specs for it. I go to the auto parts store and they can only pull up the 3.4L, not the 3.5L that my car has. Could this be the problem? I got pregapped plugs, but at the time I didnt know there was the two different engine sizes. Or could it be something else? Where can i get the right parts for it?
