The CNG Kit on my IDsi Honda City has an advancer on its CNG Kit Model Stap 78 .. It has two light green and red.

can some body shed a light on if the green and red light are suppose to be on at all times or if only the green light should be on when the vehicle idles.

can somoene also tell me when the red light on the advancer should come on ie .. during idle or when the car accelerates or when the car deccelerates

ur help would be much appreciated.
