You could have a bad fuel pump, bad fuel injector, corrosion inside distributor cap, corrosion on distributor rotor, bad ignition coil, or sevearl other things. Take off the distributor cap and inpect it inside for a white powder type of build up. If there is a build up you might want to replace the cap and rotor. Usually the cap is about $20 and the rotor is about $15.
