Any help or suggestions would be appreciated. I posted about a month ago on my daughter C230 and this is what she has had done to the car.

Changed fuel filter.....check engine light & rough running after fueling

Changed 1 coil......car ran fine for a few days and then the same rough running

Changed the other coil...again, car ran perfect for a few days and then the same

Changed all ignition & plug wires...same results. The mechanic is at a loss on what to do next...maybe a MAP sensor??? I don't know. Thanks for the replies or suggestions

 

I have a 2000 C230K and just replaced the plugs and cleand the MAF. I noticed a big difference in the "smoothness" of the engine.

 

Is your CEL on? If so what are the codes?
