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?

Please post this in the W163 area here.
Lots of info and smart owners that have solved these problems.
P0104 has to do with the mass air flow circuit being intermittent.
That may be what is setting the other codes.

Please bring your questions to the W163 forum so we go into it in detail.
