The car moves jerkily

Charge at the start of movement

Jerks when accelerating

Jerks in steady movement

With regard to the car leap - a short-term change in the frequency of spontaneous engine speed regardless of the pedal "gas". In everyday use, as a rule, there are a series of jerks. The limiting case of leap - failure - a sizeable lag response of the engine to the accelerator pedal.

There are roughly three types of runs:

- At the start of movement;

- When accelerating;

- The steady movement, ie, at constant pedal position "gas."

To determine the causes jerks when driving a car with a fuel-injected engine requires special diagnostic equipment, so please contact the service that specializes in the repair of fuel injection systems. However, experience shows that in most cases are caused by poor jerks fuel pressure in the fuel rail or malfunction of the throttle position sensor.

If you have some skills you can determine the cause of the runs themselves.
