Average Mileage: 199,037 mi (149,000 mi - 247,149 mi)


The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.

    Engine 'jerking', sometimes violently at a wide range of speeds, but always only when my foot was on the gas pedal. Solution took some time for the mechanic to figure out, but once he did a new Throttle Position Sensor fixed the problem completely.
