My 190 has a problem and its been pissin me off. When i go to start the engine in the morning it starts but runs really rough almost like its misfiring. But after about 5 minutes of driving the problem will completely go away. The car will run perfect after its warmed up. Does anyone know what this might be? EGR valve? O2 sensor? I need help PLEASE!
