That's strange. Mine doesn't cut out till about 124 and I have an 01 GTP special edition as well. Either way, I believe the only way to get past that is to change the ECM (i think). I think http://www.grandprixstore.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=PFYC&Category_Code=GP has the info you need.
Make that PCM...
I posted earlier that my 2000 Grand Prix GT was having issues with the "Trac Off" light coming on, my Tachometer dropping to 0 when the engine felt like it quit and then pick right back up. I have fixed the issue. It is the Crankshaft Position Sensor. I bought it at Auto Zone for $31.00 and replaced it myself. It is a challenge to change because you have to pull the Crankshaft pulley from the bottom of the engine. You can get to it through the passenger front wheel well. Remove the wheel, the two panels, and you have access to the pulley. If you do not have mechanical skills, I do not recommend doing this yourself. Because these engines do not have a distributor, the plates with U-shaped notches on the inside of this pulley rotates between the gaps in the Crankshaft Position Sensor sending a signal to let the plugs know when to fire. Since replacing the sensor a month ago, I have no issues with the sputter, the tachometer dropping to 0 and the 'Trac-Off' light coming on.
I had driven a 1997 Grand Prix GTP for 3 years. Last year my daughter turned 16 and I passed the car on to her. Yesterday morning I got a phone call from a co-worker informing me that my daughter's car was on fire. She had driven to her morning class at college, parked the car, and within 10 minutes was notified that her car was on fire. The car has been running fine, as I had just driven it over the weekend. No warning lights came on, and students who got to class after her said the car was fine when they got there. I have been doing some net searching and found this is a somewhat widespread problem. All the damage was contained to under the hood, although the car will be totaled. According the the fire department, it started on the passenger side, near the coil/fuse block area. This is really the only trouble we've ever had with this car. It's been a great car prior to this.
I have a 98 GTP and all 4 door panels (stapled) top trim along the window have cracked and fallen off. any suggestions how to replace those without buying complete door panels??
I purchased a 1997 Pontiac Grand Prix 3.8 last year for 2400
the car had 190,000 It has run great until last month. It started with a anti freeze leak. I was told that I had a crack in the radiator. I found a radiator place that fixed the crack? But the car is still smoking a little or is it steam? Also the acceleration is terrible from 0 to about 20 and then the car pickup is fine at around 25. There is a funny whining and grinding noise too! Also a hint of smell like something is burning, but no real smoke when I open the hood. The rattling and grinding noise is coming from the passenger side under the hood. I am 17 and this is my first car, so I am learning and somewhat reluctant to what I am told at a lot of garages since I don't know much about cars yet. I am looking for any suggestion, ideas or comments, so at least have some inclination if I am being taken for a ride by some mechanic.
I am in the market for a new car. I currently own a 98 Mustang GT, but it's killing me on gas, the rims are cop magnets ,and I keep crashing it.
I was looking at Chrysler 300m, Nissan Maximas, and a 98 Pontiac GTP. The GTP has 75,000 miles and ample horse power, but I fear I am going to buy another problematic car. Any suggestions? Do cops pull you over often? Maintenance? What should I look for in a test drive? Is the juice worth the squeeze?
It gives me hope for humanity that people are using the internet like this to actually help each other out. Thank you.
I have a 2001 GTP and love the car. Looks great, drives nice and love the supercharger whine and power. I have owned it for about a year and a half putting 42K on it. It now has 130K miles on it. I would buy another one in a heart beat, hope it lasts me a long time.
I purchased a 1998 GTP in 2002. It has been a great car. I have 136,000 miles have only been really doing any regular work on in the last 1 1/2 years. My issues are small. I'm looking for replacement parts (center console cupholders broke and weather stripping needs replacement). Could someone let me know where I could find an aftermarket supplier for dash/console stuff. Pontiac Lady... ;)
To the February 7th poster, the noise on the passenger side under the hood is your supercharger, it needs to be replaced.
I have a 1998 GTP with 106k miles for 3 years now, and I had that noise since day 1. Bought a rebuilt ported supercharger from American Superchargers by way of eBay for $500, Midas replaced for me for $250, no problems since.
Also had 3 major oil leaks 3 days after I bought the car (at 84k miles), turns out previous owner used the cheapest gas she could find, which is a HUGE no-no with a supercharged engine, use 90+ octane gas ONLY unless you like fixing leaks.
Also purchased Performance Package 3 from intense-racing.com along with a new exhaust system, and I now have 346 horsepower and 288 lb torque, which is about as far as I can go without an inter-cooler and a beefed up transmission.
I have had the intake manifold problem, which was a $1400 fix... other than that nothing major so far.
LOVE this car, and it's future includes a new crate engine, new body paint, and new leather/suede interior.
I have a 2001 GTP 4 door, and at 76,000 miles, we are having a stubborn problem with what appears to be the ABS system. It makes a groaning noise in the left front, then shudders as you apply the brakes at slow speed.
A shop we trust encountered the problem, but since it isn't throwing codes and only happens intermittently (but more and more often) they couldn't verify its cause or verify it was fixed after servicing. It disappeared for a few days, but it's back again. Anyone got any ideas?
If I know what to tell the mechanic, I can probably get a mechanic friend who works at the pontiac dealer make sure it gets done right.
Other than the ABS problem, which can be alarming, the car has been very dependable, and has had great performance. We got it with 13k in 2002, and it's been a great car if you overlook the occasional minor glitch.
Over 5 years, the passenger side window regulator was replaced, as well as a plastic trim piece on the back window (one the exterior) which had discolored. 2 years later, the replacement is just as bad... not sure why either, it's only one side it happens on.
One of the speeds on the AC/heat fan stopped working, but was fairly cheap to fix.
The superchargers don't need to be replaced because of noise of any kind. It will either be the coupler or a bearing in the snout or main case. zzperformance.com has all the bearings and the coupler. You can order a supercharger from them install it, and return yours for the core charge. Or you can just order the rebuild kit ($20) + (45,coupler) and have a local machine shop press in the the new bearings.
DO NOT go to the dealer for these issues; they will rape you. The supercharger is easy to remove. I was less irritated with it than replacing the battery.
I have a 1998 Grand Prix GTP. It has been running good until today when it came to a stop and would not continue on. The car will start and then the gas pressure drops and the car shuts off, but then immediately the pressure jumps right back up. I can start it again and the pressure drops back down. What's the deal; anybody know?
Try checking your fuel pressure regulator. It has a vacuum line going to it. Try pulling that off while the car is running. If fuel comes out of the nipple at the fuel pressure regulator, it needs to be replaced. The reason is that it is only supposed to be a "vacuum line" running only vacuum and not fuel. The diaphragm is ruptured inside which lets the fuel that it is regulating right through it which is keeping the fuel pressure low or lower making the car not run correctly.
You can get one at any good auto parts store, but I do recommend getting an original ac-delco replacement part which will last you a long time.
I am an auto technician for over five years now and I love my oo gtp. I've had a few of the issues that ppl have talked about on the thread. the latest problem I've had is stalling out intermittently with out a check engine light coming on. and today it finally stalled with out restarting which is a good thing for techs cause now I can find the problem. making a long story short I unpluged the maf sensor and it runs. so guess what part is bad and that doesn't mean you have the same problem so don't just throw parts at it... only other problem I'm having that hasn't been taken care of yet is the tranny. it has a harsh 2-1 down shift that is caused by the pressure control solenoid that's on the valve body and its only $40 from the dealer just haven't had the time to pull the trans. oh yeah for the ppl that say problems are from a lack of maintenance the trans problem didn't start until I did a fluid & filter change at 50k. other problems here and there not too bad for 65k and parts are very cheap. I drive the crap out of this car since I bought it 2 years ago. the biggest complaint I have with it is its still stock : (
