Summary:

A reliable luxury car with a small price

Faults:

I had to change one of the belts it was in bad shape, cost 27$

Fuel filter 10$

Lately the motor surges when cold.

General Comments:

I can't imagine a rolls would be any better, it is so quiet and so smooth it puts a smile on my face.

It is great car for traveling long distances, you can hardly hear the engine or the outside,wind noises is what you hear the most.

And the best part it is reliable.

The last of the full sized American V-8 rear wheel drive sedan, its the best ever made my 88 Town Car surges every once in awhile when its cold, I believe its the Throttle Position Sensor.

Does anyone know where the fuel filter in a 1987 or 1988 Mercury Grand Marquis is located? If so, please contact me or post it on this site. E-mail address is buggy13@stis.net

Thanks for your help.

My 88 Mercury Grand Marquis surges when I'm sitting at a light or stop street. What could the problem be?

Most likely cause is a dirty MAF (mass air flow) sensor or IAC (idle air control) valve.

Summary:

How fast is this thing?

Faults:

I don't know of anything.

General Comments:

I just bought this car very recently and haven't yet got it on the road. It will be in a day or so. I didn't know anything about it except it was a great deal. But it sounds like I found a gold mine. I can't wait to drive it!!! Is it really fast? What cars does it beat at the lights?

There are a lot of cars that this machine will beat at lights. But, why would anyone try to race a 4200lb luxury sedan? To each his own, I guess.

This poor old car, I shudder to think of the abuse that the kid owner will soon be heaping on it trying to see how fast it is at the lights. I bet he has either the engine or transmission blown inside of three weeks. Any takers?

The only thing I beat in my ('88 ls) 5.0 efi was another 5.0 efi. go with the 5.7 of the lsc h.o. if you want to run.

I bought a 1988 Mercury Grand Marquis GS, and it is the best car I have ever owned. The power that this car has is unreal, and to tell you the truth I've put a turbo, aluminum cam and crank, and this thing soars to be a sedan. So my deepest thanks goes to the Ford and the Mercury dealerships for making this car.

Honestly, I have a 88 Marquis that I bring to car shows. All original; exceptionally kept with 59 K miles. It has hit 98 MPH with my GPS, since the speedometer only hits 85. I would not take this car any faster, or really gun it at all. You try hauling 5400 LBS with 200 HP. It's made for cruising and taking on trips. Not a redlight burner. Unless you seriously soup up the engine, chances are you will mess it up pretty bad.

Honestly, for that being a show car, you know very little about it. The stock 1988 Grand Marquis weighs less than 4000 lbs. And the 302 V8 put out 150 HP/270 pounds of torque stock with the Ford 5.0 Liter 302 V8.
