I have a 1999 c230 Kompressor, in the morning when i start up my car it seems to make alot of noise like running rough. Also from start till I reach around 20 mph it runs a big rough and slugish. The morning here are warm around 65, so i know it isn't the cold. I have replaced my maf sensor. replaced spark plugs. new air filter. new oil change. Fuel injector cleaner. Could it be a motor mount please help me with your info. thanks

Make sure the plugs are in correctly. Make sure the wires are not loose.

Make sure everything is connected, and there are no loose vacuum hoses.
