2000 Mercury Grand Marquis Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2000 Mercury Grand Marquis

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.

A spring in the seat belt buckle may wear or fail, causing the airbag light on the instrument panel to illuminate. Failed buckles will require replacement.

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.

There are four oxygen sensors on a 2000 Mercury Grand Marquis. Are the front two the same part? Are the back two the same part? Or all all four sensors a different parts?

Also replaced intake manifold and starter. The engine runs good and is quiet the car has 228,250 on it. Please Help!

I'm in my 50s and have owned 4 other vehicles over the past 35 years - all Dodge/Chrysler products - some of which were ordered factory new, some of which were used.
