Before I buy a new MAF sensor, am I missing anything?
My 330ci has a terribly rough idle and sometimes it runs totally ragged right up through the rpm range.
When I unplugged the MAF sensor it idled perfect. I didn't drive it that way though. I probable should.
Cleaning the MAF sensor made no difference.
So. Is that it? Do I just need a new MAF and that's it? Any other ideas? Should I get the codes?
