    P0302 is misfire detected on cylinder 2, P0304 is for cylinder 4.
    The best way to test the fuel injectors is with a noid light.
    Plug the light into the injector harness and attempt to start the car. The light should flash.
    If it doesn't, you'll want to verify that power is getting to the injector. If you have power but no injector pulse, you may have a failed ECM.

    This link should help:

    I'd focus on the ignition system--ICM, coil, distributor cap, rotor, spark plug wires, and spark plugs. If the problem persists, I'd focus on the distributor housing.
