share-97 Marquis Throttle Position Sensor Problem
Just wanted to share. Have a 1997 Grand Marquis. Car has 248,000 miles original motor and transmission. There was no response from accelerator pedal and the car would barely stay on. Only codes I got was P0420 & P0430. Replaced throttle Position sensor TPS. Cost $28 at Autozone. They had a cheaper one for $24. Problem went away. Also cleaned air flow sensor.
