I have a 2000 mercedes c230 kompressor. I bought it about a year ago. The mass air flow sensor was bad so I changed that and made the car run like new. I also put in a new fuel filter. Now the car has hard trouble starting. keeps dying. keeps stalling and lagging. smells like dumping too much fuel maybe? can this be the mass air flow again?
I would try cleaning the MAF and see if the conditions change. I have read about after market MAF's failing faster than a stock unit and causing idle and run issues.
