1990 Pontiac Grand Prix Turbo 3.1L MPFI V6 intercooled turbo


This is a great car, definitely a good buy, and it's a rare car


Rust on the alternator pulley.

Paint chipping.

Vacuum leak, so vents don't work right.

Power antenna failed.

Tape player fails to eject tape, and the radio won't work with a tape in, but the sensor inside thinks there's a tape in there still (we got the tape out).

Cross over pipe cracked.

Cat converter going bad, smells of rotten eggs.

Lip on front bumper breaks easily.

General Comments:

Nice looking.

Takes premium gas (damn!).

Very fast.

Low miles.

Seats are extremely comfortable.

Heads up display, so it projects your speed on the windshield.

Rear bucket seats very comfy.

Tons of trunk space.

Sunroof / moon roof combo.

1990 Pontiac Grand Prix LE 3.1


A couple of months after purchasing the car, everything went bad:

The fuel pump.

About 5 sensors.

And the computer.

It took forever to find out, because once the computer found a bad sensor, it would stop the diagnosis. It cost over $600 to fix.

Fast forward to the summer of 2004 and a few minor repairs later...

The shift cable snapped, dealer only part costing nearly $200.

Five days later, the car quit firing. Someone told us it was the crank sensor. Who knows!

This is just a repeat of when we first got the car. It was running fine for over a year and then just quit again, just turns over and over without starting. We are now going to play the sensor game again.

General Comments:

Very expensive car for up keep.

Seemingly reliable engine.

Nice looking car.

Although expensive for repairs, I guess it is cheaper than a car payment!

1990 Pontiac Grand Prix LE 24 valve DOHC MFI 3.1 V6 Bored to 4.3


A well made car if you know what your doing with it


When I purchased the car. It wasn't in running condition. It had no brakes -- meaning no rotors, no pads, and no calipers. The power steering pump needed to be replaced soon after I had gotten it running again. The car has eaten three alternators (I finally decided to go with one with a lifetime warranty). The car has also gone through two fuel pumps. The speedometer no longer functions (my fault for that). The odometer has yet to function. The odometer has yet to function. It shows the same mileage from when I purchased the car. The car was purchased at a Police Impound Auction in Mississippi.

I payed 1200 for the car. Since then I have put close to five grand under the hood and have drag raced the car in Huntsville. My car currently get 9 MPG on the highway she gets close to 15 MPG

Its not the cars fault its the modifications that I have done to it.

I love my car I use it to race, and drive daily to work, school, and the occasional street drag.

General Comments:

The car is no longer the stock 3.1 V-6 MFI It is now-- 3.1 bored to 4.3, 24 valve DOHC Mulitport Fuel Injection. Injector upgrade (36% injector out put increase), Port and Polish performed. Oil cooler and Transmission cooler installed. The 4 speed auto has been replaced with a 5 speed semi-auto transmission. The lower half of the engine block has been replaced with the 4.3 from a 2002 Blazer. The car is currently pushing 324.6 Hp. (tested /w Dyno) And the cars current top end is 181.4 MPH (Tested at Huntsville) The cars last Drag time was 9.7836.

I believe people do not understand the LE the car is a light body style with a large engine. Sure I know every car will need basic maintenance every car does. Like brake pads, oil, and tuneups.

I have built this Grand Prix from the engine out and I haven't found a better car yet. I understand the car by the sound of the engine and I never puch the car more than I know what shes capable of.

I would recommend a Pontiac to anyone, but if you don't like to get your hands dirty don't buy an LE.

If your planning to buy an LE I realize you can't base any real good information off of my review. This review is to show you that the LE is very capable of anything you want to use it for, imagine the possibilities. :)
