Can any one please tell help me. I have recently started experiencing problem with my civic RPM when on CNG. It drops when I apply brakes or when idle.
This issue started a few days earlier. It works perfectly ok when on petrol i.e. rpm stays at minimum of 900. One strange thing though, when I fill CNG from peshawar, the RPM at idle is again at 900(or 800) but when I fill from Islamabad/Rawalpindi, the RPM drops.
Please Help, I cant drive the car anymore. I tried to manually tune it by a mechanic, but it didnt worked
