I took my 05 in yesterday with 31k miles on it. I just started having problems with acceleration. They advisede me when I purchased it at 17k miles six months ago that it was totally up to date on all maintenence and would not need to have any work (beyond oil changes) until after the normal 36k miles as they had done everything. So now they are stating that the fuel system needs cleaned, and the vehicle needs a tune up. What kind of spark plugs are recommended for my vehicle? What is suggested for the fuel system. I usually use just regular unleaded and every once in a while i'll throw in some higher octane if it seems to be running rough. But at this point I need to know what's suggested for maintenence.
