Car was throwing throttle pedal code replaced w 3 from junk yard and finally broke down and bought new one from mercedes. Still didn't fix. I've put new coils new o2 sensors before which helped drastically but still having problems with throttle positioning sensor in foot pedal, all wires appear clean and intact no other codes showing as of now but runs like crap. Any suggestions
