CAR (engine) vibrate under load at 1700-1900RPM only...
Hi,
My 07 CLS550 make a strange vibration specifically between 1700-1950rpm. The most noticeable situation is when I am crusing on highway at 60mph and I try to accelerate slowly, it feels like it`s ''rumbling'' up to ver the 2000rpm mark and then gets smoooooth... I don`t get any code so far, no CEL... But the best I can describe this is it feels like bad ignition coil or missing fuel...... Other than that, the engine and transmission is flawless all up to the red line...
