94 c220 rpm fluctuating PLEASE HELP!!
Lately my car has been acting up, and was wondering if you guys could help. The problem I'm having is when i give it steady gas the rpms bounce back and forth (mainly between 1500-2000rpm). This happens while driving and in park. Another thing i noticed is that the OBD2 scanner rarely ever connects. Can this mean that i have a bad ECU or is it something else? Besides this, the car idles perfect and has good power.
Things i already replaced:
engine wiring harness
cleaned MAF sensor and throttle body
vacuum lines look ok, and seems to have no leaks
