#931 of 980 Re: 98 Grand Prix, key stuck in ignition [racer32x] by miramichi Sep 06, 2006 (6:41 pm)
Replying to: racer32x (Sep 05, 2006 5:31 pm) I know what your going through! Under your steering wheel on the column you will have a small square hole, about 1 1/2" wide. If you stick your right middle finger in this hole with your palm facing you, you will feel with your finger nail a small round button. Push this button in and your key should turn all the way off. You will have to do this each time you shut the car off. If you look by the square hole I told you about you should see a small round hole also. This hole is lined up with the little button inside. Take a screw that is lone enough and put it in this hole so it keeps the button pushed all the time. Heads up! keep an eye out for some "shift lock release" problems in the future.

A few months ago it stopped running and wouldn't start.A buddy of mine who is a mechanic told me to replace the crank sensor so I did.problem solved,well its only been about 3-4 months and now car is spitting and sputtering real bad.It was doing it before the crank sensor went out and now it is doing it again.Can a crank sensor go bad that quick or could it be something else?But it is doing the same exact thing as last time.should I replace the crank sensor again?PLEASE HELP!!!!! thanks Replies to this message: momwag (Sep 09, 2006 8:33 am) ntfstenuf (Sep 09, 2006 4:17 pm) mmxer (Sep 09, 2006 6:34 pm) and 1 more... naseem641 (Sep 20, 2006 6:11 pm)

Replying to: ntfstenuf (Sep 08, 2006 11:23 pm) Have you replaced the plugs and wires? Might check the ignition coils as well. Replies to this message: ntfstenuf (Sep 09, 2006 4:17 pm) mmxer (Sep 09, 2006 6:34 pm) ntfstenuf (Sep 10, 2006 9:34 am) naseem641 (Sep 20, 2006 6:11 pm)

Replying to: momwag (Sep 09, 2006 8:33 am) Thanks for info.I bought a new crank sensor and installed it in about 10 minutes.problem solved,when I took the sensor out it had a lot of oil in the connection area so it must of cracked.runs like a champ now.new wires,platinum plugs about 3 months ago.I was told that the 3.1 engine was junk but I've had the car over 2 yrs. and only prob was the crank sensor.Overall good car.Thanks Replies to this message: mmxer (Sep 09, 2006 6:34 pm) ntfstenuf (Sep 10, 2006 9:34 am)

Replying to: mmxer (Sep 09, 2006 6:34 pm) The hardest part of the job was jacking the car up with a scissor jack and taking the tire off.You can't see the sensor you just gotta feel with your hand.All it took was a 10mm deep socket and ratchet and a new sensor.The first time I did it it took a while because I didn't know what I was doing but after that it's like riding a bike,you never forget.Is there any hop up parts for these year cars?just wondering if anyone knows thanks.
#939 of 980 Stalling Issues when accelerating/decelerating or when Idle? Try This!! by ken7308 Sep 10, 2006 (10:20 am)
I have a 99 Pontiac Grand Prix GTP Super Charged 3800 Series II Engine. I was experiencing stalling issues like a mad man. When I'm at a red light it'll stall, when im at a stop sign it'll stall when i accelerate from a stopped position guess what? Yep, it stalls. I tried everything from changing the MAF, Spark Plugs, Cleaned the throttle body, tested the fuel injector you name it I did it. One last idea came to mind and that was to check each cylinder coil and module. I took the cap off of cylinder 1 and 4 and it was pitch black! Meaning it was not receiving constant sparks from the plugs which cause all of my stalling issues. I call the dealer the wanted to charge me $586.00 plus tax to change them out. Well guess what, Im not even good at working on cars but I was able to change the cylinders and module by myself. Very east to do on my car. The parts cost $21 for each cylinder and $127 for the module. Car is running like a CHAMP!!!(knock on wood!! : )   Hope this helps anyone with stalling issues. Thanks for all of the help you all have given me.
#940 of 980 funny shifting-only sometimes by falster Sep 12, 2006 (7:30 pm)
I recently bought a 2001 grand prix gt. Everything is great (well there is that weird key stuck in ignition thing-but i know how to fix that anyways) the only thing that worries me is every now and then when accelerating the shifts seem a bit jerky, accompanied by an almost inaudible whine. Otherwise the car shifts smooth as glass...yes, the tranny was serviced at 76,ooo mi. it now has 93,ooo mi. so that shouldnt be the problem right?? i heard it might be the computer increasing the pressure in the tranny but why would it do that? any help please? thank you Replies to this message: naseem641 (Sep 20, 2006 6:16 pm) falster (Sep 21, 2006 7:14 pm) lkerr (Sep 26, 2006 1:10 pm)
