The sound is so low, I can hardly hear it when I put my ear to it with only that speaker dialed in with the fade and balance.

Does anyone know what would be the cheapest method of replacing the speaker?

The DIC in a 98 Grand Prix GT I'm helping to sell is flashing zeroes in every category. This happened directly after the ignition switch was replaced. I keep finding references online that they are related but haven't found out how yet, or how I could fix it.

The ABS light went on as well as the traction control off light. I checked for codes from the obd, none were displayed, but I didn't know if those would store or code there or not.

Also at the same time the radio display went out. It still works on the HUD, but I saw someone mention that searching online that they might be related.

Unrelated, the SRS Airbag light has been on in this car for 10 years. It's been checked out more than once and was found the airbag system was fine. Is this a common thing?

I have a 2000 GP with 3.1 engine. When the car is first cranked up, it runs perfect. As soon as it gets warmed up, it shutters between all shifts as long as you have the gas pedal pushed down at low speeds and low rpm. Give it more gas and the shutter stops. It's also started the shuttering while driving at speed between 55 and 65 mph. And it does it really bad while going up a hill unless you give it alot of gas. The exhaust seems to have a little bit of a " putter " effect when you put your hand in front of the exhaust pipe, sorta like a miss. I don't know what to do with it. Anyone have an idea that could help me? Also has new intake and head gaskets and held pressure fine on a test. thanks! ]]> Grand Prix dedhowy http://www.automotiveforums.com/vbulletin/showthread.php?t=970649 http://www.automotiveforums.com/vbulletin/showthread.php?t=970646&goto=newpost Wed, 18 Nov 2009 01:07:57 GMT Hey guys, I want to perform a tune-up on my 109k 2000 Grand Prix GT and found decent prices at the follow link, so I just wanted to confirm these were the correct part numbers.

This thing stopped on a dime. I did noticed that the rotors would warp a little though. Well the day came when the rotors and pads needed to be replaced. So to try and get around the warping, I went and got some drilled and slotted rotors....off of....ebay (I know, I know.) :shakehead They sure looked cool when I first put them on, but then my braking distance about doubled. My Jeeps stops WAY better than my car does and my Jeep has crappy brakes. Well that was a few years ago and the time to replace these things will be coming up soon. So I have a couple questions. First, the rotors: Should I get regular solid cast rotors like I had before or should I get higher quality drilled and/or slotted rotors from somewhere else? On the pads, the best stopping I had was when I was using ceramic pads on regular rotors. The only problem was the the rotors wore down fairly quickly and would get rather hot. I like the look of drilled/slotted rotors, but heard that you have to use soft pads on those kinds of rotors. I know I have soft pads on right now (they came with the rotors), and they are wearing fine with no warping to the rotors, but I also have no stopping! :uhoh: The bottom line is that I want the best stopping power I can get without my rotors warping after a few weeks. Any suggestions? Thanks! :jump3: Hi All,

I've got 106k on my 05 GT, and have this intermittent problem where i'll start the car, and go to drive it but it has no power and surges with light pedal input, and bogs down when you get on it. Turn the car off, restart, and it works fine. This happens like every 10th start, doesn't matter if its a cold or warm start. I've been digging around the net trying to find others with this issue, but it doesn't seem there are many cars of this vintage to get high miles on them yet. I've found a few reported issues and people blaming the transmission, PCM, traction control etc... but no exact fix.

I think I may have found the culprit though. I believe it is a problem with the "drive by wire" throttle system. Its as though the PCM is not getting the correct throttle info when this happens (no check engine lights though). Has anyone ever replaced their gas pedal assembly? Its basically the pedal attached to some sort of electronic potentiometer box and looks like an easy part to replace. I saw there was a TSB somewhere (not sure of the number) that stated a similiar issue and the dealer was to replace the gas pedal assembly or throttle body to fix. My gas pedal has always been rather stiff as well which leads me to believe it could be the source of the problem. Also sometimes it will start and it will take very little throttle input and the car flies, most of the time it drives with what i would call normal response and then sometimes i get the no power/stumble issue (kinda like when traction control turns on where it surges the engine). I've removed and cleaned my TB, and all sensors are clean as well.

Trouble is finding a gas pedal assembly for a drive by wire car (malibu, G6, grand prix) is not easy to do used. And then there is the issue of a junkyard car also having the same problem. I'd like to find one and disassemble the electronic component and see if it needs to be cleaned or if resistance can be measured from the input like a TPS. Anyone attempted this or is this a fools folley? I can't find one locally and they are $50+ on ebay used so its alot of out of pocket to test this hunch. I don't wanna take mine apart because its my daily driver. Let me know what you think, thanks! ]]> Grand Prix coolzzy http://www.automotiveforums.com/vbulletin/showthread.php?t=970379
