I have chevorlet Enjoy purchased one year ago andgot it converted to CNG.
Nowadays my car is giving problem of increase in rpm during running. It accelarates automatically but comes back to normal after few seconds. This problem is mainly observed in 2nd gear.
When we referred this problem to our CNG fitted company they said the IC valve is to be replaced. Chevorlet did change the IC valve when noticed problemistic.
Bt then also my problem isnt solved. Where isthe actual problem. Chevorlet people say they need to investigate this.
Could u please help?
