Ml320 running rough please help
I have a 2002 ml320 that is running very rough. When I am driving and come to a stop the car will bog down and normally recover. Sometimes the car will stall and die as well. This does not happen all of the time. I took it to a parts store and got it scanned the came up with the codes P0172, P0175, and P0104. Last year around this time I have two of the spark plugwires replaced and that seemed to help for a while. Does anyone have any ideas?
