Question about 2004 Pontiac Grand Prix
I have an 2004 Grand Prix with 181,000 miles on it and recently got the Reduced Engine power light and codes p0068 and p0101 after searching the web I wound up cleaning the the throttle body and MAF sensor with no luck, but after finding out where the fuel filter was I changed it, which cured the problem. How embarrassing, I have owned this car for 9 years and have had it serviced regularly, but never before changed the fuel filter. I sure the other stuff helped but the fuel filter fixed the reduced engine power problem. I had to disconnect the battery each time to get it out of limp mode and was quite frustrated at the end.

Possible problem could be a corroded main electrical connector. Open the drivers door on your Pontiac. On the side of the dash is a panel that can be removed. Remove it and disconnect the electrical connector in there. If you see the terminals corroded or green, then you have a water leak problem causing your problems. If your Pontiac has a sunroof, that is most likely the cause. Clean up those terminals and see if that fixes

Hi It me Mohammad Siddiq my dear. First of all it will be wise of use to take your vehicle to a dealership or any other fully equipped w/shop. They can better tell you what the fault your vehicle has. But at the same time if your friend has the same model vehicle so you can exchange some parts with that vegicle, e.g., Mass Air Flow or TPS (Throttle Position Sensor) and can check your vehicle. These parts do not need to be programmed with scan tool. Just Simply replace these parts and switch on the ignition and wait for 01 minute, then switch off for 30 seconds and then start the engine. Now road test your vehicle, if no SES light or reduced power then there was fault with the part/s replaced. So Return those parts and now you must replace these parts with new or used ones. Anything else I may be contacted on my yahoo id email@example.com. Thanks. I am an auto technician and working in a GM dealership in Saudi Arabia. I am from Pakistan.

SOURCE: My 2004 Grand Am GT Stereo Issue
I had the same problem when I changed out the factory cd player. I finally found the problem was that grand am gt cars have a couple of amplifiers with crossovers in them for the speakers and the after market stereos put out sound that has been slightly amplified already and when you hook up your new stereo to the wiring harness your sending amplified sound from your stereo the the factory amp then to the speakers this sometimes messes with he sound and clarity of the sound. My car is 2002 and the factory amps are located 1 under the glove box and 2 in the trunk behind the carpet on the drivers side. The amp and crossover in the front is to split the signal for the door speaker and the tweeter by the mirror and the amp in the trunk is to split the signal for the two way speaker in the back by the back window witch if they are like my factory speakers have 2 wiring harnesses connected to each speaker. the only way I could get mine to sound good was to run new wires from your stereo directly to the speakers and bypass the factory amps. This may not be the only way to fix this issue but it was the only way I could figure it out. I hope this helps

Go to autozone.com create a free account put in you cars model year etc... then look at the free manual for replacing head gasket it will have a bolt tightening sequence diagram. also they usually have to be taken off in a paticular sequemnce to avoid warping the head. If aluminum heads they usually recommend new head bolt set and having the head shaved (Leveled)
