Recently i purchased a baleno 2003 model, the car is good indeed but have issues like backfiring and slow acceleration on cng in 2nd gear (without ac), it has done 200k ....
I got the car checked by a mechanic and he told me not to go for new coils(for back firing) as it will cost me around 16k and the same issue will arise after some time even if i don't wash the engine, instead he advised me to convert it to carb cam(which i believe came in the earlier models of baleno's) and that will cost around 12k and assured me that , by dong so i'll get better millage and pick.... currently the car gives 160km in 55kg cylinder.
Kindly enlightened me... what will be best in said scenario...
PS: the car has FF CNG and starts directly on cng n the cng switch is manual, and as per my observation the car's advancer is removed.
Thanks n regards
