Santro BackFire Problem on CNG Only

I have wasted alot of money going to different shops and even to Santro's own service center in Rawalpindi and Islamabad but they could not fix the problem.

My Santro Executive 2004 model used to back fire on CNG and then its air filter box would open up with it. In the start, a tuning would fix the problem only for a week and it would again start. On Petrol it works perfectly without a problem.

Then the problem wouldnt get solved, so I changed the plug wires and it fixed the problem only for a month and again it started to backfire on CNG. I had to change my wires twice again and it seems like it will go on. All the mechanics do is change the wires.

My two questions are:

1. Where does the fault exactly lie since its happening again and again and i cant keep on replacing wires?

2. Telll me a GOOD place where people can REALLY fix problems of such CNG issues and not only do a temporary fix so they can see and fix the problem.

I had the same issue with my Santro. After lot of research changed the plug wires from open market but after a week, same issue raised again. Finally once again changed plug wires but this time bought wires from Hyundai dealer and placed original air filter as well. Problem was resolved and since last 14 month no problem so far.

I wonder if you bought plug wires from open market or Hyundai dealer?
