Okay... K&N drop-in filter, NGK V-Power plugs (and NGK wires), run tires 2-4psi over manufacturer's recommendation, replace fuel filter anually, use a good fuel system cleaner every oil change, use synthetic oil in the crankcase, transmission AND differentials, drive with windows up and A/C off (just vents), drive 55mph on freeway (this one is HUGE), slow acceleration and try not to drive short distances. These are all "hyper-mileage" techniques that garner better fuel economy. If there is a mechanical problem causing the fuel economy to be bad, the spark plugs, wires and filters ought to be a help.
i hope this helps out,

No, there is not one available. However, the Chevy Trailblazer is basically the same vehicle and there is a repair manual available for that.
