Spend $60 on a hand held ODB II reader instead. The most common code set by vehicles is a fuel system code that gets set when you don't tighten your gas cap down all the way. You absolutely can get shop manuals for new vehicles (for GM anyways, I imagine Ford and Chrysler are the same), it's just not cheap and you have to know where to look.
