1992 Mercury Grand Marquis LS 4.6 Liter V8

Summary:

A Lincoln for the price of a Pinto!!

Faults:

The windshield wiper motor went, the wipers were stuck up on the windshield, so had to replace that, $75.

Had to replace the spark plugs and the wires, because the car was missing so badly, $230.

Had to get an oil leak around the oil filter assembly fixed, began to leak when I put a higher viscosity oil in the engine, $50.

The car also burns a slight amount of oil, maybe a quart every five thousand miles. One of my friends who used to be a mechanic at a Ford dealer, told me to switch the oil to Mobil One 15-50, but to only use one quart the first time I changed the oil, and two the next, and so on until it was all Mobil. Also when I had to add oil to only add Mobil. This has seemed to help the oil burning problem as I have only had to add about a half a quart of oil in five thousand miles.

Also I had to get a leak around the front passenger side wheel well fixed, as when it would rain water would get into the floor of the car and cause the carpet to get wet, $175.

General Comments:

I love this car, it is so comfortable, it is great on gas, I went approx. 500 miles on a trip (to the mountains, many hills going up and down with cruise control!!) and I got an average of 31 miles per gallon, I could not believe that with a big V8 with over 100000 miles on it.

The engine runs so great and there is so much room in the car and the trunk is huge, this is a great car for traveling, and it rides really smooth.

1992 Mercury Grand Marquis GS 4.6L SOHC V8

Summary:

Bargain reliable Highway cruiser

Faults:

The AC system refurbished.

The engine at 100k started to burn a little oil. It uses about one quart every 5,000 miles.

The alternator failed at 80k and was replaced.

The paint has begun to chip and fade, the car was never garaged.

The front Brake rotors replaced at 100k.

Replaced sun damaged headliner in 2001.

General Comments:

The interior design lacks finesse, but the car is very comfortable. This car is a very good highway cruiser.

Gas shocks made the handling improve to satisfactory, the car has good acceleration and highway performance.

Every power accessory is still operating, the interior fabric as a whole has held up very well.

Hi, I have also a mercury Grand-marquis 1992 GS, and the paint is very cheap. I think that the sun burnned my paint like that. But I painted it this last summer. I have 213 000 kilometers in my odometer. The engine take a lot of oil, but not smoke. I put two litters of oil whit 5w30 and one litter whit the 10w30. I use the Valvoline Max Life. It's a good oil, but I thought that the engine would take less oil, but isn't in their publicity.

I have a 1992 grand marquis and the odometer just stopped working... what is the problem.

L need some advice. a neighbor has a 1992 Mercury Grand Marquis which had several problems when he bought it.

The previous owner only drove the car for local shopping and never drove it on the highway.

My neighbor was offered the car for five grand and he bought it. It only had 35000 miles on the odometer. He soon had to replace the wire harness, the catalytic converter and the thermostat. Bills came in at 3 grand.

He now wants to literally give it away for a few thousand dollars because he was told the car needs a new computer card.

My question.. is this too risky to consider or should l take a chance. The car only has 40,000 miles on the counter.

I do a lot of highway driving, if that's what this car needs.

It's almost like a new car in appearance.

Any advice???

Steve.

1992 Mercury Grand Marquis LS 4.6L V8

Summary:

Good affordable family sedan

Faults:

I have just bought this car and already things have gone wrong with it. The check engine light comes on when you are driving long distances and then proceeds to buck. The front seal in the transmission is leaking and the transmission its self shifts roughly into overdrive. Other than that we love it. I always told my self I would never drive a Ford, but here I am driving one. I would recommend this car to others interested in purchasing one. The 4.6l V8 engine in smooth and fairly powerful. This is the same engine used in police cars, so they must be reliable. Fuel mileage is actually not too bad for a big car. I like Dodge better, but they or chevy no longer make big family cars like ford does.

Thanks for reading.

Hi To all!

I just purchased a 1993 Grand Marquis with 60,000 miles on it and is doing all the mentioned symptoms, (check engine light when at high speeds, Goes to Overdrive without notice, Bucks and vibrates every now and then)

Has anybody found the causes of these glitches?

The engine and transmission are in perfect condition and I think it may be a (flow, pressure or oxygen) sensor problem, but before I go and spend a fortune changing all the sensors at random, I would like to have some light on the issue, or have an idea of what to look for.

Other than that, I just plain love the big ride and comfort that 4000 pounds of steel provides on the open roads.

Any comments will be greatly appreciated.
