    I am having following problem since last month in my cultus 2011 make VXR EFI Factory fitted CNG.

    The car starts well on pertrol and after conveting to CNG, (some time it gets four led lights and some time only 2 led lights) it goes for 0.5 to 1 km and them leds starts to drop and after showing red light the car stops. It start again on petrol well and do the same thing....

    and the funny part is when my car is in good mood it not only shows all four lights but give me adrivin on CNG as normal........ I have driven 50 kms when it is in good mood....

    seems your cng kit / switch is not getting proper voltage as it happened once in my civic and a technician installed some relay with the CNG kit and it is ok since then .
    something fishy about number of total posts !!!!
