hi people
i am driving a tx3 1996
my car jerks when i step on the fuel pedal slowly or even when it's idling....the rpm would go down and up a little bit...this cause the car to shake even when it is not moving.

If your problem is like mine..then u are in for a big headache. My jerking problem is water in the fuel tank and fuel injectors.
