I have a second hand 1993 grand prix which I just bought recently in an auction. it was running well at first then I brought it to a car wash to have it cleaned, but when I came back to get it it wouldn't run anymore. It's running right now, but very poorly. I have to force it to make it run. the engine is noisy. the fans are not working and the SES light is lit. there are times, very rarely, SES light turns off and the car will run smoothly and so will all the fans and aircon, but when you turn it off and use it the next day, its the same problem all over again. I'm very frustrated already...I'm hoping someone has an idea of what's going on with my car... help needed...ms jet.

I bought a used 1998 Grand Pr ix GT two years ago. In that time, I have bought new brakes, new water pump, new alternator, two or three new sensors not to mention that I am having a problem with the car spontaneously hard-shifting and the tacometer stops reading. I hate this car. I'll never buy another Pontiac. The one I have has dollar-ed me to death.

I have a 97 Grand Prix SE with a 3.8 V6 and its been a good car, but I'm having an electrical problem. I was wondering if any one has had the same problem. When I put the blower motor on low or medium speed my day time running lights go off and I have to operate the headlights manually.

My 97 grand Prix SE is an electrical nightmare I will never again buy a pontiac. The key won't come out without manual override. The shifter won't come out of park without manual overide. When the wiper blades are on it kicks out of cruise control. The radio volume is intermittent. The engine electrical system gets weak then shuts the car down with a fully charged battery, not allowing a restart without a jump, then everything works fine for about a week. The fuel gauge does not operate correctly under a quarter tank, it jumps back to full. The right electric window is intermittent. The only excitement Pontiac brings is not knowing if you will get there or not!

As far as the Service Engine Soon and the rough running, you may have a short in the ECU (computer), which controls the idle, fuel-air mixture etc.. My friend has a 95 GTP and experienced the same problem. Worst of all, they aren't cheap, but that's probably whats wrong.

I have the same problem with it cutting out. When I changed the spark plugs and the wires, I found build up on the dist. terminals. After cleaning and replacing plugs and wires it worked great.

The clicking starter thing could be your solenoid, My Z34 had that problem and it was that. The idling problem when cold is probably your intake manifold gaskets, I replaced those and it fixed my sputter/surge and cold idle problem. I'd also suggest changing the timing belt atleast every 50K miles. Just suggestions, good luck with your car.

I have a quick question, I have a 95 grand prix and for the life of me I cannot get this car out of park, does anyone know if there is an override switch to get this car out of park, or anything else I can do, thanks.

Hey there, I was wondering if it is possible to maybe fit a small block V-8 into a 1996 Grand Prix GTP, most likely a 350 of sorts?

Any information would be appreciated.

I too have a 95 Grand Prix and I had the same problem with the engine getting stuck in park. I was told that there is a switch in the column that has to be replaced for the shifter to work properly. either that or maybe it is a fuse.. either way I actually took a hammer.. yes a hammer, and gave it a good hit and since then it don't get stuck no more..

Hello there

We own a 1994 Pontiac Grandam- My Wife ritually gets the oil down at the local oil / lube shop, well they told her that we needed a radiator flush, I could have done it, but oh well we needed it. 2 days later the car is heating up. We added radiator fluid, which looked low. still heats up with in 20-30minutes of driving it seems like it still driving OK, but I did notice they gauge was off the chart and when lifting the hood it sound like it was hissing, but it felt like it was driving OK.

2 Questions.

1-could it just be ready wrong and is only hissing because its hot because its normal.

2-is there a thermostat I can change out, I need your help son took third car back to college and we are down to one car.

Thanks Mike.

Mike, I don't trust "lube shops" because the people working there are usually on the questionable side as far as knowledge. My opinion, which is why I would do my own maintenance, or go to a real garage. The connection between them working on it, and your newly discovered overheating problem is too big a coincidence to ignore. Probably they did not fully refill the cooling system after draining it. They never do. Never. They all say they do, but they never wait for the thermostat to open and push out the air bubble in the cooling jackets, and consequently they are about two gallons short when you get the car back. I hope you have not been driving it far with the temperature gauge buried, because if you did, you have probably already warped the aluminum head. Hissing is never normal. A buried temp gauge is never normal. The hissing is steam escaping from a leak somewhere. If you are very lucky, you might just have a loose radiator cap, or a pinhole leak in a radiator hose. The hissing is steam escaping, and when the cooling system loses confining pressure, the liquid flashes to steam and your temperature goes up. Try to dim the lights in your garage and use a flashlight to search for the steam trail. DO NOT DRIVE IT ONE MORE MILE before fixing the leak or YOU WILL BLOW YOUR ENGINE.

I own a 2002 Pontiac Grand Prix SE it has 179,000 miles on it. My SES light is on and my fuel gauge always jumps, I never know when I am low on gas. Sadly I have actually ran out of gas a few times because it said I had more than I really did. My gearshift also got stuck I also have to manually take it out of park. Any help with this would be greatly appreciated! Thanks.

I have a 95 Pontiac Grand Prix SE. Over the last few months I have replaced several hoses, the thermostat and the water pump. The problem is that now every time I try to drive it the temperature gauge goes over the 260 mark before I even go a mile. There is always plenty of water in the radiator and the engine runs just like it always has, no sputtering, or anything. I have had the oil checked for water in it and there is none and no water or smoke coming from the exhaust pipes. The car does have a busted heater coil and the hoses have been temporarily re-routed until I can get it fixed, but I can't figure out why it is overheating the way it does. If anyone has any suggestions they would be appreciated.
