guys i am having a trouble. when ever i drove my car on CNG it given check engine light. i have done with CNG kit service, throttle body service, Plug cleaning etc. CNG mechanice attached computer with my car and saw that this is Oxygen sensor alarm but he said that ur oxygen sensor is working properly, this is a comon issue in City 07 model so its not at all dangerous
that check engine light appears randomly. like sometime twice a day sometime once in a week. but as soon as the alarm appears i stop the car. shut it down, restart it and Alarm just wanish away.
can anyone guide me whats the issue?
i have got filter changed as well. after filter change i didnt get check engine alarm for 2 weeks but now its again there.
