2001 Mercury Grand Marquis Problems

Throttle Position Sensors May Fail and Cause Engine Performance Problems

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.

Intake Manifold May Crack Leaking Coolant Behind the Alternator

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

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.

2001 Mercury Grand Marquis Reviews

Got car used 4 years ago. Only problem I'm seeing are the intake manifold gasket as mines was just replaced after my car stalled at stop sign. Good Luck to other previous owners with this problem.
Can an oil leak stop my starter from working?
This car has been reliable. 4.6L is a great engine. power windows very slow up and down. side electric mirrors stopped working.Other than that good car.
