Next you may want to put in a new fuel filter if you still have the original; that is the quickest and cheapest way to fix plugged up fuel flow. If not that then fuel pump and/or injectors are much more $$$.

May be obvious but sometimes new spark plugs work wonders; a new crossover wire set may be in order too if never replaced yet. Stay with factory parts for the plug wires.
