A few questions
My car will not exceed 100/ 110 KM/ h (60/ 65 MPH), burns a lot of fuel, my mechanic says it is missing an " air regulator valve"... The part has 2 wires..what is this part, and what function does it do in the fuel system? My engine came out of a 90+ model W 124, it has a 2.3 liters displacement
