1991 Mercury Grand Marquis Problems
The car had 64600 miles on it and the headlights started going out while driving, which can be very dangerous. The problem is in the Light Control Module which is an expensive part (around $500 to $600 + labor).
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.

ilove this car
A great Ride anywhere, Highway or across town. They dont make them like this anymore. A great family car with plenty of room.
my tranny has reverse but no forward gear does it need to be rebuilt or just an overhaul? Other than that i love it only has 34,500 miles.
