You are in the Pontiac Grand Prix
What is this discussion about?
Pontiac Grand Prix, Sedan
Nov 02, 2004 (4:10 pm)
I have recently had a problem with my '01 grand prix SE 3100....there has been a squealing noise that i believe is coming from the left front of the vehicle near the axle. I has now progressed into a thumping noise that gets louder as i get faster. The noise isn't really thumping but it sounds like your in a supertuner with a exhaust that never shifts out of first. I believe it may have something to do with the axle bearing or the cv joint but can't pin-point the problem. My friends 2000 grand prix gt has recently started the squealing noise so i was hoping a fellow pontiac driver might know the problem.
BTW-the sound goes away when i take curves to the left.

Yeah, CV joint or bad wheel bearing. If it goes away to the left, you are loading right and easing off left, so look on the left side for the problem.
#83 of 980 99 GTP Ticking/Rattling Noise
Nov 09, 2004 (11:01 am)
99 GTP with almost 60 k miles
When accelerating b/t 2500 - 3000 rpm
I hear a ticking / rattling noise coming from the engine. It is most prominent after cold starts, but sometimes lasts for over an hour.
Of course when I brought to the dealer, it made the sound the whole way there but failed to make it with the tech in the car.
Any ideas what this could be?
Also, what is a PCV valve's function, is it important to replace, and when should it be done?

Sounds like perhaps an exhaust leak from the manifold? Sometimes this type of manifold leak will "swell shut" when the engine gets hot enough.

So I have been a frequent poster on Edmunds for my Chryslter 300M and Jeep Grand Cherokee and just took a look on this site for my "old car" which I have owned since new in late 94 and always babied and done every maintenance work on time ... one reason I am frustrated by this problem.
My 94 Grand Prix with 3.1 L V6 may have been demonstrating this "piston slap" noise problem since new. It has always had valve noise when cold, and the past 4 years started burning more oil. Of course this is a 11 year old car with 111k miles now so I really don't expect much other than to try and find a reasonable way to salvage it for my son that wants it for his last year of high school and driving to college. A couple mechanics say just drive it running rough as it is until it conks out (especially rough in the winter, takes a long time to warm up and even semismooth out) - they figure it needs either a valve job, at least valve guides or maybe rings. Not worth a fix in the $1000 range for a car not worth $2000. But hard to find another car I'd trust in that price range, I have even considered dropping in a newer 3.1L from the junk yard as the basic car is in pretty good shape (but who knows what shape that's in?).
Your lemonaid link gives me a server error. Is there any other way or easier way to fix this problem?
#86 of 980 (ABS), Check Tire Pressure, and Low Trac lights
Nov 27, 2004 (7:24 pm)
This is regarding my 1997 Grand Prix 3.8L. When I start my car and begin to move, I hear a one-time mechanical clicking sort of sound from the front drivers side and all three lights (ABS, tire pressure, and low trac) turn on. Even though the clicking is one-time, the lights will remain on until I turn the car off. Has anyone ever heard of this problem? Thanks for reading.
#87 of 980 94 GP 3.1...Please Help!!!!!!!!!

I've posted before (#76), but didn't get any help. Same car, an updated question.
I think I have eliminated just about everything, except the ignition switch. I even tried a new key with the same resistance as the original one.
Someone once told me, you can eliminate the resistor on the ignition key if you measure the resistance in ohms across the key (1.13k in this case), get an inline resistor, cut a wire from the ignition switch and install the resistor.
If anyone knows of this method, could you please post. Also, if this is the case, would I have to remove the resistor on the key itself.
Thank you for your time. Mike.

The ABS controller is detecting a fault and shutting the ABS off. A scan tool is required to retrieve any stored ABS trouble codes, but my bet would be a defective wheel speed sensor, which is integral with the wheel bearing/hub assembly.
#89 of 980 98 Grand Prix GT - Groaning noise in winter
Dec 01, 2004 (9:49 am)
I've owned my Grand Prix for over 6 years now and it's been pretty trouble-free so far. But it seems like every winter (since about 2000), I get this groaning noise in the front left when going over bumps at slow speed. It gets a tad worse each year...but I don't think it's a real big problem. I was just curious as to what it might be.
I'm thinking it might be something with the struts, but I'm not sure. When I go over a bump, it kind of groans like somethings rocking back and forth...and then eventually settles after about 2 or 3 groans...depending on the size of the bump.
Any ideas? Is that a strut problem?
#90 of 980 Radio problem
Jan 18, 2005 (7:05 am)
I have a 01 GT with factory radio “CD player included”. The channel select display/clock doesn’t work anymore. Owner’s manual is no help, anyone know if there is a fuse not listed in the manual that might have burned out, or is this a terminal problem.
