My 300E - 1988 off suddenly close to 40 MPH.
The fuel filter is less tank 5000 kilometers. The Idle is OK close to 500 RPM. Air filter is clean. Idle Control Valve clean.
The Pin2 voltage at AIR FLOW Pottenciometer is 700 Milivots, DUTY CYCLE is 50%.
I will check the fuel pressure Tomorow.
Please help me.
