I have a 2002 1000cc vitz (CNG Fitted) , from past few months i am facing weird problem in it,
My car runs perfectly fine on CNG but its missing on petrol,
i could hardly drive on petrol as the car vibrates alot and therz alot of missing in it, but on CNG it is fine.
I got its fuel filter cleaned last week, that day the car was running fine on petrol but the very next day it started missing again.'
I am very confused about it, if anyone of you could help me out with it.
