1993 Mercury Grand Marquis Problems

EVP Sensor Failure May Cause Drivability/Fuel Economy Issues

The EGR valve position (EVP) sensor can fail on this vehicle. The EVP sensor measures the EGR valve position and transmits the date to the engine control computer. If it fails, drivability and fuel economy can suffer, the Check Engine Light will commonly illuminate.

Engine Performance Problems Due to Failed Throttle Position Sensor

The throttle position sensor (TPS) may fail. Common symptoms of a defective TPS can be rough idle, hard starting, hesitation on acceleration, poor fuel economy, and stalling.
