CNG Backfire Problem

My CNG idle was not set properly so get it adjusted at a mechanic, shortly after that every few starts on CNG it back fires makes a LOUD firecracker sound and burns part of the air filter. In the process it also knocks out a pipe and the car wont stay turned on even on petrol.

Anyone know whats causing this backfire and how to correct it? Dont like the feeling of knowing at any random time the car could break down!

Hello!
Mixture plays imp role in that.....all you need to do is to adjust mixture as fine as you can to get rid of backfires......!
or it will blow up your air cleaner box or burn the whole air cleaner.....!
which car was it.....problem mostly occurs in almost all new cars with box type air cleaners and Efi engines....
Thanxx
