#570 of 980 Re: 2005 GP Vibration in front end [scapagliata]

Hey Scapagliata, I'm with you on that LAST Pontiac deal. I just stumbled across your posts while trying to find an answer to why my 2000 Grand Prix developed a bad vibration. The vibration on my vehicle is only when turning right and accelerating and I was wondering if anyone figured out what your problem was??? I have been to several different mechanics, the last one is one i trust but is several hours away. He told me that he checked everything on this car and can find nothing wrong with the vehicle. He told me that the only thing that it could be was the transmission, what do you think??? This has been going on for months and has cost me alot of money and has fixed nothing. Luckily, he is going to put on a used transmission to see if this fixes the problem. Ill let you know how it turns out.
If anyone can answer these questions let me know, Im beyond frustrated.

Hey Scottmo (are you in Missouri?)....sorry you too are having trouble. I've replaced nearly everything but the motor and transmission in the front end. The "certified GM Pontiac Dealer" believes my problems have nothing to do with the engine nor the transmission. I took it to the tire place first. Started there getting new tires. This didn't resolve the issue. So we replaced struts, then bearing/hub assemblies, lower tie rods, and had it aligned. We also had new plugs and wires installed by a trusted mechanic. He couldn't tell anything was wrong with the car. Nothing we did made even a hint of difference. So I took it to the Pontiac Dealer...FOUR times. First they said it was the lower motor mounts. Those were replaced and it made no difference. Then they said the motor looked like it had dropped. Visually you could see it was tilted back and toward the right. The altenator pulley was next to the resovoir tank on the passenger side. So, the frame guys hooked it to gauges to determine it's placement, and decided it was definately out of place. Something had to be bent. $200 later, they found the cradle was bent and they bent it back into position. The motor is sitting in the right spot, visually it does look better now. But....no change in the vibration. Now they say they are nearly convinced it has to be the right CV joint is bad or perhaps the axel is bent. They recommend replacing the entire axel assembly, have it realigned and I "SHOULD" be ok. I've spent over $1000 already doing things that "SHOULD" fix the original problem. What's another $200 right???? Anyway that is my next plan, can't stop now. Will try to get that done in the next week or so. If it doesn't fix it, then my plan is to just drive it till it falls apart. The car looks and sounds like a new one just sitting there. Starts good, runs great. One thing I've learned, is now a days unless there is some type of warning light, check engine light on, where they can hook the computer to it and make the accurate diagnosis..... you are just paying for educated guesses. And I do mean "PAYING". Good luck. Let me know what you do that fixes your problem.

I have had this problem with my 98 grand prix as well. here is how you fix it without changing anything. first buy a can of brake cleaner (spray can) pull out the little rubber under the ignition. Spray up and over all the column inside, be very generous it cleans the gummy switch that causes the whole problem. If it doesn't work right away repeat the process. Spray alitte in the ignition as well if or when the key is out. Your friendly mechanic Curtis curtis_whelanhotmail.com

I too had this problem with my 2000 grand prix gt... it started around 68,000 miles too. Finally it got where the key relased very easily. So easily, in fact, that you can remove the key while driving down the road. I was told they could replace the ignition/code/remotes/keys for $400 but I declined. Sometimes it's a pain, others it's a convenience. I can leave the car running, pull out the keys, lock the doors, and run inside to pay for gas and the heater keeps the car warm while Im inside. Gotta look for the bright side righ? I've learned to deal with alot of quirks with this car. I've driven a Pontiac for 15 years. Had a grand am first drove it for 230,000 miles and it was still going when I traded it. Had this one only 3.5 and have had constant frustrations with it since around 60,000 miles. This will be my last one.

OK THIS IS IT.... my last post I hope. FINALLY!!!!! IT'S FIXED!!!!! Thanks to my HUSBAND. Today we replaced the right and left axel assembies (cv joints too). It was a long tough job, but it was do-able and it's done. Drove the car, and outside of it needing a new alignment, it drives like a new one. Odd thing is that each time we asked a mechanic to diagnose it..even the pontiac dealers mechanics, we asked "could it be the cv joints?" and each time were directed to another cause. Should have listened to our own 'guess' and started there. Could have saved about $1000.00 in parts, tires, and a tune up. There was no visible sign the axel or cv's were bad. But it sure made a difference. I can't tell you how relieved I am. If you are having a shimmy or vibration in the front, and an alignment doesn't solve it. Try the cv joints FIRST...then work on the other things. Good luck.
#575 of 980 Dying, Not Starting & Hesitation
Jan 10, 2006 (5:27 pm)
I have a 2002 GTP w/ 62k on it. I replaced the battery this past fall as well as gave it a tune up. About a month a go I was going 70 down the highway, it started to hesitate and the RPMs dropped to 0 and stayed there and the TCS light came on and stayed on. I drove it home turned it off and it started back up again with good RPMs and no TCS light on. While sitting at a light last week it died. I put it in park tried to start it (it turns like it wants to start every time). It took about 4 times and finally started. Went to my parents house this weekend (1/-1/2 hours away). Drove fine the whole way. Let it sit about two hours. I went back out and it wouldn't start. Started right up the next day and has run fine since. Does anyone have any idea what's going on with my car?

I have a 1998 GTP with 210,000 miles. I have had no problems with the supercharger. The only thing I have had to do is replace the belt and tensioner due to normal maintenance.

#578 of 980 Check Gas Cap Light/Chime in My 2004 Pontiac Grand Prix GT
Jan 12, 2006 (2:14 pm)
The Check Gas Cap Light/Chime in my car came on,as did my Engine Light. My boyfriend took it to Advanced Auto and they plugged a small computer to my car, which came up with code P0455 EVAP Emission Control System Leak (Large). So he got a new gas cap and then they reset the code for my car and it was fine. I put gas in my car and later that day the Check Gas Cap Light/Chime came on again and has been on ever since,but the Engine Light has not come back on. The cap is on the right way, we checked to make sure. Does anyone have any clues as to what is wrong with it?
Jan 12, 2006 (7:34 pm)
It seams I lost the use of my super charger. It happened about 2 weeks ago. The interior Boost does not register any more and I donít have the acceleration I used to. There doesnít seam to be any noise coming from it. Any, suggestions please.
