1)- when I start my car its computer some times does not give the pulse to its CNG/petrol switch, after a time interval (ignition switch off) approx. 5 min its CNG / petrol lights glows (ignition re on) then engine starts.
2)- when engine convert on CNG its timing shows 12 degree that should be 17 to 18 degree. Its advancer might not be worked.
will you please guide me?
