I have a 1998 Grand Prix GT with a dual turbo charger in it. Boost gauges and mods out the roof.
When I bought the car, I had to put a new engine in it because the gaskets leaked and there was water in my oil, which meant that my intake manifold kit was pumping water into my cylinders. It also threw a rod through the hood of my car.
I would name off all of the parts I put into the car, but it would take forever, and I have to go to work.
But my Grand Prix has 859 horsepower and 500,000 miles on the body. And it is still holding up, and I have to say the 45,000 dollars I put into it was definitely worth it, so if you have a Grand Prix with all kinds of problems, don't get discouraged, keep adding on to it.
I'm only 16 and it was my first car. Me and my dad worked on it, putting old Camaro parts on it at first, but then we just bought new parts from HKS most of them are.
Great car and I will never get rid of it. I will have it until I die. I'll never ever sell this car, it's already ten years old and it will be worth a lot of money when it turns into a antique.
I love my car - 0 to 60MPH in 3.4 seconds. That's right, be jealous hahaha, but seriously a great car.
I got a 1998 Grand Prix GTP supercharged. I was driving and it shut off, and I replaced the coilplate / coil/ and fuses / and all spark plugs, and it's still doing the same. It won't start / can someone explain what is going on with my car?
I was driving, hit a curb, and the fuel pump stopped working. Is there a fuel cut off switch, and where is at?
I have a 1999 GTP with about 175k on it. Just purchased in January. After replacing a few needed things (tires, mufflers, mass air flow, tune up... it runs like new! Now, this weird thing started: When under load, there is a loud clicking/clanking sound coming from seemingly the left front wheel area. It will drive fine in any gear, at any speed - when I go easy on it, but when I put it to the floor, it makes this loud sound and it feels like something is slipping. I can make it happen at 20mph or at 80mph - I tried revving while coasting in neutral and no sound - only when in drive and when I stomp on it.
Heeeelllp! I want to save this car.
OK, I just bought a 1998 Grand Prix GTP. It ran great, but now it will start, but shut off after a few seconds. Fuel pressure is @ 40 a little low. Any ideas out there?
OK, GTP with the noise under acceleration 2 posts up... I just replaced the CV axle - didn't help. Is this some weird bearing symptom?
My TCS/ABS hasn't worked since I bought it - I don't think it's related. Wires were cut on the bearing/hub assembly due to poor install. Brake light starting to come on and off in the last week. Again, not sure if it's related - it's driving me crazy!!
I can see that nobody actually responds to these huh? Kind of like putting a message in a bottle and letting it float out to sea...
Sounds like you're having transmission trouble. My wife's 1996 Delta 88 has the 4T60E and I think GM built a heavy duty version of it for the supercharged 3.8. Her transmission made some noises similar to what you describe and then finally quit pulling. I pulled it and upon dis-assembly found that it contained some stamped steel parts that weren't fully hardened. I'd never seen such light duty parts in a transmission before. But I was used to c4 and c6 and turbo 350 and 400 trans. I put $400 of aftermarket parts in it and it works fine now. It was a very easy transmission to build.
OK, I've been reading some more... what about the Pressure Control Solenoid Valve Assembly? There's a bulletin from July '02 that sounds like it addresses similar symptoms. Just not sure if it's exactly that.
I have a 2002 GP GT Coupe, it's an awesome car, I've had many cars before and yet this one is very nice.
The car has right under 80,000 miles and the only problem I have is the transmission. It shifts so hard when it's warm. I took it to a million places and at the end it says late shift ($1300) to fix. it cost less to put a trans in it. I'm a GM fan since I was young, and this car's transmission problem annoyed me. I've had no problems whatsoever, even though I have a sound system in the trunk that weighs roughly 180lbs, it doesn't effect the way the car drives at all.
It's probably PCS related common problem with 4T65E transmissions. Your check engine might be on. The PCM commands max pressure because the computer reads the solenoid engaging shifts to slow. You should probably go to an automotive forum if you want get detailed info. This website is more for car reviews.
I have a 1998 Pontiac Grand Prix, I just put in an engine from a 2001 Pontiac Grand Prix. The car keeps shutting off on me, the mechanic said it was my EG valve. He changed it but the car keeps shutting off. Has anyone ever had that problem before. Can someone please help?
I got a 1998 Pontiac Grand Prix GTP, and my heads up display and radio will go off and on. What's wrong with it?
