Atif Siqui Came to my office and we had a spin on his Baleno. The car was giving jerks and uneven idling along with backfiring at times.
Now after some adjustments, it seems fine and drive has gone smooth. I suspect Plug wires are showing signs of age as the car is over 2 lac Kms driven and still wires are stock so replacement will be a good idea.
It was nice meeting mr. Atif again and we had a good chat about PW over a soft drink.
