2006 BMW 530xi when you push on gas it wants to studder (chug chug) then about 60/70 seems better.
Cranks ok. Ideals rough. Doesn't want to go chug chug until about 60/70 runs
better. I got it up to 120 mph and seemed okbut when I slowed down at stop
sign started all over again.
Sounds like you need a tune up. If your BMW has more than 100,000 miles on it your due for a tune up. I'd try that first. HTH. -Jim
