Hello my issue is When im driving my c230 the car bogs out if going past 55mph . Im thinking its the mass air flow sensor.
But im not 100% sure car runs good throws me a jerk once in a while putting it in gear but dont think its the tranny because it hasnt just shot on me and it dosent jolt at stops like its fighting to stay on ...my car runs smooth but sounds like it runnig rough or high .any advice is much appreciated.

 

Is it loss of power and do u feel loss of power going up hills or when flooring it? If so it could be a plugged cat.

 

Since your car is OBD2, try pulling the codes to see where the issue is originating.
