#4379 of 4431 2005 Grand Prix emissions by flyboy107 Dec 06, 2007 (6:19 am)
I have an 05 Grand prix that just failed its inspection due to a P0411 code that came up in the emissions test. I was told by the dealer over the phone that its a secondary air injection check valve that need to be replaced at a cost of $300 for just the part!! Are there any other cheaper options it might be? Is the dealer blowing smoke up my butt?
#4380 of 4431 2001 Stalling, not starting and Tac to 0 by jsimssd72 Dec 11, 2007 (12:52 pm)
I noticed about three months ago my tac on the console would drop to 0 and stay there while the car was still running. Once you stopped and started the car it would work fine. Then the past two weeks I have had issues with the car not starting right away. It will turn over but not start and if you wait some time it will start for you. Also it has stalled on me about 3 times this week. After reading this I think I am looking at the CrankShaft sensor. IS there anything else I should look at based on your past experiences?   Thanks,
#4381 of 4431 Tilt wheel lever by dlc2 Dec 12, 2007 (7:45 am)
I am trying to gain access to the steering column to replace the solinoid that releases the key. I have a 2003 Grand Prix and haven't been able to find a way to get the tilt wheel lever removed so I can take off the steering column cover.   I've read there is a clip that holds the lever in place on older models, but I don't see it on this one. It looks like one piece of plastic. Any ideas how to get this out? Thanks Replies to this message: timinator (Jan 15, 2008 7:23 am)
#4382 of 4431 1998 Pontiac GTP RPM to Zero/TCS Off by 767fo1 Dec 17, 2007 (11:56 am)
My 98 GTP RPM will suddenly drop to zero and occasionally the TCS goes to OFF. From what I have read, it appears it could be the crankshaft position sensor or the cam sensor. Anybody had any luck replacing these parts without further problems? I also hear they are not that easy to get at for replacement.

#4383 of 4431 Valve Tapping??? by zofsharick Dec 17, 2007 (1:18 pm)
It sounds like a valve is tapping on my 03 GTP. It did this month ago but went away after it warmed up. I changed the oil and it completly went away. Now its back! This happen to anyone else.   Does anyone know how much this is going to cost to fix? Replies to this message: cargirl30 (Jan 01, 2008 12:41 pm)

Replying to: zofsharick (Dec 17, 2007 1:18 pm) Sounds like the oil pump may be failing. I have had this happen. I had to have my engine rebuilt because I didn't know my oil pump was only partilally working. My lifters would only tap sometimes and it was usually only after I started it, then would stop after a minute or sooner. It would be fine after I changed the oil and then a few days later start all over. Sounds like you might have the same problem. I hope this helps!
#4385 of 4431 GT 2001 by cigsmh Jan 08, 2008 (5:42 am)
I purchased my Grand Prix in 2004 as a used 3 years old car. Recently had to replace head casket and this is the only problem I had. Very reliable car. Very fast and very predictable on the road. The breaks is fantastic. They saved me twice from a very serious accidents Car is very fast and very big. I drove a Camry 2005, and its cabin feels bigger. The trunk though , is huge. I am going to replace this car with a SUV, but I like my car and its a pity that GM can't put a normal head gasket on 3.8 and 3.4 engines. Engines are very economical and reliable
#4386 of 4431 Re: 2001 Gr Prix GT Odd Problem [dgw7245] by wbeard6 Jan 12, 2008 (10:58 am)
Replying to: dgw7245 (Dec 05, 2007 6:00 am) I have a 01 GP GT. Back in July, had the same problem as you, took my car to the dealer, they said I had a bad left wheel hub. $500 later car seemed fine. 3 weeks later, same problem; took car back to dealer, they said the other front wheel hub was bad; another $500. Now 3 months later, problem is back. Are the dealers just guessing? A lot of people seem to have this problem. How many more parts will we pay for before the problem is diagnosed correctly? I am extremely frustrated! Could it just be the wiring to the harnesses or the wheel sensors? Assumed the dealer checked these when replacing the hubs. Do you feel the "rub" in the steering when straightening the wheels after backing out of a parking space, and does it seem to happen mostly when car is cold?

Replying to: dlc2 (Dec 12, 2007 7:45 am) I just replaced the ignition switch on my 2002 Grand Prix and also had to remove the tilt lever. I found that the lever simply comes out if you pull firmly on it. There's nothing holding it in, it's simply a friction fit.
