I am having lots of problem recently my my Mitsubishi Lancer! Causing backfires (patakha, miss) on CNG (and burning/making a hole in airfilter)
Went to many CNG guys, some did adjustments, one told me to change the coils (which I did.. situation improved for a while but problem is back), 1 changed the plugs (normal plugs)...
On petrol, its totally fine..
I read somewhere to use Iridium plugs! Will that solve the problem? Anything else?? If yes, where and cost?
Thanks in Advance
