Start by checking ignition components - Plugs, wires, cap and rotor (if that car has a cap and rotor)
Inspect all your plugs. If the one in cylinder 4 is dramatically different from the others, there may be something going on in that cylinder that is fouling the plug.
If there is no obvious cause in your ignition system, then I'd check the cyl 4 injector.
