I have a Wagon-R VXL with 12000 mileage on odo.
Since past month, I have been experiencing jerking when I press accelerator. It is obvious most of the time in 1, 2, and 3 gears. It seems to be fine in higher RPMs. Some times the car runs smooth without any problem. The jerking starts all of a sudden when go to lower gears and try to accelerate. At that, even if I press pedal to floor, the car wont get acceleration.
I do not think it is because of bad fuel, as it runs smooth most of the time.
What could be causing this problem?
Thanks in advance.
