Help! 540 poor idle and maf issues.
I recently changed my 528 for a '98 540. The car performed perfectly until 2 weeks ago when the car occasionaly stalled when comming to a stop. A few days later it did not idle at all. I cleaned out the icv and all seemed well again except for an occasional hesitation when accellarating hard. But idle fault is back! The car now peforms better when maf is unplugged! The car picks up speed like it never did. But occasional poor idle. Could the maf be faulty?
