Just a warning, get this problem figured out right away... I made the mistake of letting it slide.. and now I need a rebuild...
I got this M3, it runs good for one exception, it has a rough low idle. The idle goes up and down, not drastically though, but enough to bother you.
What do you think is the problem?
