:confused: Hey guys, I got the SES light, when I am driving, the engine hesitates below 2000 rpm with lumpy idle, but once I get past 2000 rpm, everything seem to run fine

Did a code read, it showed a few occurrences of rich conditions.

I replaced the MAF's recently, along with new O2's, and new plugs

Car is a 2003 M5 with 50,000 miles, full Supersprint header, cats, pipes, mufflers, LTW flywheel, otherwise stock

I erased the code, car drove fine, but about 30 min and the same code came back, and again it hesitates below 2000 rpm

Any ideas/experiences with similar issues?

Your help is greatly appreaciated.
