1990 Pontiac Firebird Trans Am 5.0 from North America


All problems aside, I love this car


Had to replace the original alternator.

Replaced cracking serpentine belt.

Replaced driver's side headlight motor.

Replaced transmission mount.

Replaced brakes.

Converted air conditioner to 134-A.

Got seat covers to cover holes in the driver's seat.

Trunk motor and light are broken, haven't gotten around to replacing them.

Fog lamps need a new fuse.

General Comments:

The car handles great.

It's very reliable, all the problems I have caught before they were problems, except for the alternator.

I don't think that the cabin is uncomfortable, there is a lot of leg room. However my friends and family have complained about the room, and my sister with long legs has a hard time crawling out.

1990 Pontiac Firebird Formula 5.7 TPI from North America


It will put butterflies in your belly... the


Anti-theft key system failed.

Has blown 4 transmissions. (since I bought it)

Knock Sensor failed.

Oil sending until failed.

Door pins/hinges constant problem.

General Comments:

This car will grab your behind and slam it in the seat. I have run this car very hard in the 2 years I've owned it (drag racing, street racing, etc.), and it still holds up just fine. A few modifications such as custom exhaust, K&N air filter, and air foil were cheap additions that made her even more powerful. WS6 suspension is a dream, it handles batter than any car I have owned. It is such a beautiful car that to this day when I look at it, I can't help, but almost drool. The interior as well is very pleasing.

It has led me to be involved in a few car clubs, meeting wonderful people.

For the guys: This car is a serious chick magnet! It seems everywhere I go, somebody wanders over to me to talk about this car.

Only two warnings to potential buyers...

The 700R4 transmission is simply not strong enough for this car. I advise a seriously built one, or a totally different transmission such as a TH350. Also, be sure it is already equipped, or prepare to purchase Sub-frame connectors. The car has too much torque and will actually crack on the back roof corners from the frame twisting due to the power.

Next time you blow your transmission have them put in an internal shift kit. It should help some.

I just purchased a 1990 firebird formula. It has a 350 tune-port injection under the hood is there any thing I should watch out for? I only paid a $1,000 dollars for the car. Iam about ready to start restoring her to her original. Any advise would be helpful.


1990 Pontiac Firebird GTA 5.0 from North America


It's nothing special now, but when I get some $ flowing, it will look nice and go very fast


As a well maintained 1990 Trans Am GTA, numerous things have gone wrong. A year after purchasing my GTA, my left-side injector harness shorted out (costing me ~ $1000 and several weeks).

Not long after, both my AC compressor bearing, as well as my alternator bearing seized up, and in one instance created an engine fire while on a freeway.

Other little things have broke (usually during the cold months), such as the hatch-back release motor, the driver's side mirror-motor, and the dash-vent system.

Currently, I am facing 2 issues with my GTA:

1) While starting the car, the starter seems to stick (making a loud growling noise).

2) Sometime the car won't start completely, due to a security feature gone haywire. Allowing a 5 minute period before trying to start it again tends to fix this issue (although not very cool while on a date!).

General Comments:

Call me crazy, but I still love my GTA despite all these problems. I haven't gotten too wild with it in terms of "maxing it out", but I have taken some pretty sharp turns (WS6 style!). One time I was frustrated with all these problems that I revved the damn thing up to 5,000 RPM right in my work-parking lot. As you might expect, I turned a lot of heads!

You have a GTA with a 305? Every Grand Trans Am I've seen have 350's in them.

I have/had a 90 GTA with a 305, it was a great car... was in an accident a weeks ago and the car was written off... as the numbers of the 1990 trans am GTA's slowly decrease the prices got up. FACT: only 1183 1990 Trans Am GTA's were ever produced 884 in the United States and 299 in Canada.
