My wife's computer is reading "Power Engine Low". What is this? Thanks for your thoughts.

I got the same trans problem you got with the annoying oscillations during accelleration. I have tried real hard to find any info on the net about it and it seems that you have the same problem I do. Too bad I cant find a fix for this one. I would like to fix it myself or have some ammo before I take it to a dealer. Please post a fix if you get one in the future. I will do the same. Thanks, Dave.

I have had four Grand Prix's -- 1995, 1999, 2002 and now a 2006. All were GTP's, except for the new car which is a GXP. My nephew has had my 1999 until about a month ago. It also went on fire and the fire dept. could not save it. He had left it across the street from his office for an oil change. Five minutes later, someone called him and said is that your 1999 Red Grand Prix. He said yes. They said it's on fire. The hood was so hot that the fire dept. had to cut it off to remove the engine. He does not know what caused it. It happened five minutes after he turned the ignition off. He also had to fill out a lot of forms and the insurance company said that they would give him what it would be selling for from the dealers in his area.
#446 of 980 Supercharger tension arm rattle/clatter, Hesitation fix!!
Oct 25, 2005 (4:00 pm)
Re: posting referring to hesitation. I own a 97 GrandPrix GTP with 178,000 km. After my first major tune up, my car developed a hesitation, bucking type problem when the engine was put under a load, i.e. pulling up a hill, aggressive acceleration, etc. When I was just driving steady, the car worked fine. The solution: I replaced the spark plugs and spark plug wires and the problem disappeared. Before I got around to replacing the wires, I would pull the old wires off the spark plugs and put them back on making sure I had a good connection. This would help for a while. The problem seemed to be more with the wires than the spark plugs. Good luck to all those with the hesitation problem.
I now have a head scratcher. The tension arm that holds the supercharger belt seems to have developed a chatter/rattle at low rpm's. When I'm sitting at a red light in drive, it clatters away. If I increase the rpm's ever so slightly it goes quiet. Also if I turn the steering wheel either way, the clatter gets worse. Again, this is only at low rpms (just under 1000) while the car is in gear. When I put my hand on the tension arm spring case it feels like something is hitting it on the inside. This is confusing as there are no real moving parts. Now here is the catch. I replaced the tension arm and the supercharger belt and there was no change. I continues to clatter. I did notice that there is an arrow on the tension arm and there appears to be marking that this arrow should fall between. I checked on some friends GTP's and their arrow is between the marks. I have turned the tension arm to try to put less tension on it but it almost seems like the replacement belts are shorter than the original. On my car the arrow is just outside the marks when the tension is on. Is this really a tension arm problem or is the chatter a symptom of something else.
Has anyone heard of this problem before? Sure would like to hear from you.
My next challenge is replacing the valve cover gaskets. Looks like I have to tear off half the engine to get them off. Oil on the exhaust doesn't smell so pleasant.
#447 of 980 Re: 2004 GP GT - whining/whirring noise from front of vehicle at slow speeds [bsprix05]

I have the same whining/whiring noise as well, coupled with that is a semi-violent shifting from one gear to another. When I took the car in for a Trac light problem, they clipped a line or plugged something up to fix that and I hadn't had this transmission problem since, but it reappeared yesterday. It's intermittent....usually shows up in rush hour traffic type driving, but not always.
That's on top of my latest problem; the fuel gage has decided to go nuts after 90,000 miles. No warranty on any of this I suspect.

We have the same hesitation problem on our 2000 Grand Prix for about a year now. I have tried changing the spark plugs twice. It seems to help for a short time but the hesitation comes right back. It really is anoying and seems like it could be a major problem and leave you on the road somewhere. Anyone have any ideas or solutions to this problem?

THEY HAD ALREADY REMOVED THE MOTOR AND RESISTOR AND I TOLD THEM TO LEAVE IT OUT AS I WOULD BE REPLACING IT, ITS NOT A HARD JOB EVERYTHING IS RUNNING GOOD NOW BUT THERE IS A SMALL WIRE OR LINE HANGING DOWN THAT I DONT KNOW WHERE ITS SUPPOSED TO HOOK UP TO , I THINK IT HAS TO DO WITH CONTROLLING WHICH VENTS THE AIR BLOWS FROM, I CANT SEE ANYWHERE TO PLUG IT INTO , IF ANYONE KNOWS WHAT THIS IS AND WHERE IT GOES ID APPRECIATE YOUR HELP, THANX

Please turn your CAPS LOCK off. Most people ignore message written like this, as it is too hard to read and is also interpreted as "shouting".
