I bought baleno 2005 jxr couple of days ago. It was giving backfire problem when i try to pick up the car on cng with AC switched on. If i switch off the AC the problem is gone. I had it checked by a mechanic and he said that air controller is missing so that is why it is having this problem. He then put on tape over the point where pipe from engine connects to air filter. After that car was running fine for last two days but today it started to give the same problem .
Can anyone tell me if it is teh problem with air controller? If yes then how much it will cost?
I also want to know about good baleno mechanic in Islamabad.
Thanks
