I have a 07 Grand Prix w/ 79000 miles. I have had it for a few years now. First off i was wondering what steps do i have to go through to get the steering shaft replaced for free being that it has been replaced before?
The bigest question I have is the car is supercharged. In the manuel it does say you are to use the highest octane fuel. Up until last year i always used it I then started having some starting problems. It would roll over and i live in Wisconsin so first i thought it might be the battery because of it rolling over really slow. I then replaced the battery and it still did the same thing. I then was at a gas station needed fuel but it did not have the higher 91-93 octane. I then put at least the 89. I found that my car was starting better. I have used it since. I have never changed the spark plugs but i was told most of them are 100000 plugs i have looked at them and they are decent, the gaps aren't a huge difference. Lately it has started to chug a little and you can see the rpm jump a tiny bit and feel the car shake while idling. I am also seeing low gas mileage number. I am not sure if this would be something major or what. I just hate to take it in and pay that 100 dollar diagnostic for a bad sensor. If it is something major maybe still on the 1000000 power train then i would not hesitate but even if you are like me and can USUALLY fix it myself then i get kinda sick for paying that FEE. If anyone can help me that would be huge. A LOT TO READ!!! I AM SORRY...
