possible problems: bad gas, need plugs cap and rotor, dirty injectors, pressure loss at fuel pump, dirty fuel filter and last but not least --- VALVE ADJUSTMENT ---
Valve adjustments were a required step with all Inspection 2's and in my opinion should be done every 50K. Some people ignore having that done and some places don't do it when you take the car in (even though they charge you for it). You could probably stand a good tune up (plugs,cap,rotor,maybe plug wires,fuel filter and valve adjustment).
