Within the past week my 2004 X3 seems to stutter upon acceleration. It is a manual and seems to be noticeable when shifting between 1st and 2nd gear and then from 2nd to 3rd gear at approx. 2000/3000 rpm. It is subtle for now and maybe just 3 or so stutters/shakes then drives normal. It feels...

I finished all the stems, gaskets, etc. and am stuck with three codes and some rough running. I am a bit stuck here and have tried all I can think of (and read on these fine forums) to get a good running motor. The strange thing is, when I clear the codes, and restart the car - it runs fine for...

Hi All, Im having issues with my e38 735il non-vanos, built 10-1997. The issues stem from a lack of acceleration, when I put the pedal down in normal driving conditions it seems quite zippy (2000 rpm >). But when attempts to accelerate past that 2000 rpm barrier occur, they are normally met...
