If your car has a throttle position sensor, you should clean it. This is a simple process that can fix many problems with your car.

  1. Open the hood of your car and remove the air cleaner and throttle body.
  2. Disconnect the negative battery cable from the car.
  3. Remove the throttle position sensor from the engine by disconnecting it from the crankshaft pulley (if there is one).
  4. Place the sensor on a clean surface and wipe it down with a dry cloth or paper towel to remove any dirt or debris that may have built up over time.
  5. Replace the throttle position sensor if it is damaged or if it has not been used in a while (it should be replaced every 5,000 miles).
