    Default Seeking Suggestion!!

    Dear PW/CNG experts!!
    I have a vti civic 2003 on CNG. When i start it in the morning, it starts on petrol but then in a fraction of a second, converts to CNG itself as it is an electronic device. The reson i guess for this sudden transfer from petrol to cng is that the engine gets exceeded artomatic rpm, unlike when in some cars, the transfer occurs when you press the accelerator. Because of this sudden transfer, the engine gets off and in winters has to be started atleast a couple of times.............I am unaware about the CNG settings in these EFI cars, so need your kind suggestion if this is normal behaviour for my vti or can it be called an issue and solved..
    thx in advance!!

    @gm-kazi
    thx bahee for the advice. please tell me does pushing the accelerator disables the automatic choke. because if does, i believe car would not transfer to cng this sudden as that is so because it converts to cng only because of the automatic throttle.

    THE THING IS THAT WHEN U START THE CAR NEXT SECOND IT WILL TRY TO CONVERT TO CNG IN THE PROCESS AS THE CAR IS COOL SO IT WONT PICK THE CNG QUICKLY RESULTING IN I WILL TRIP ,IF U PUSH THE ACCELERATOR IT WILL PICK CNG EASILY .AS FAR AS THE HIGH RPM IS CONCERNED IT WILL INCREASE 200 TO 300 REVS ITS CALLED AUTO CHOKE IT HELP THE CAR IN GETTING IT OPTIMUM TEMP FOR THE DRIVE
