I don't want to start adding a bunch of crap to the fuel system because I know that's not the problem. There is NO WAY I should be having this many problems with a brand new car (less than 9,000 miles). The dealership told me that I didn't keep enough gas in it (I keep at least 1/4 tank - sometimes it might run a little lower) and that is why there is carbon deposits. But I have a 1999 GMC Sierra and havent had this many problems with it in the 12+ years I've owned it. I do have everything documented in case it comes to GM having to replace the car.
BTW... Mine is Inferno Orange with white rally stripes... I absolutely love that color.
