All tho, it may have ben a fluke and is cleared up. You can go to Auto Zone and use their scanner to clear the code which will reset the check engine light. But if it comes back on and you get the same code it would be:P0304 CHEVROLET - Cylinder 4 Misfire Detected.... Possible causes - Faulty spark plug 4 - Clogged or faulty fuel injector 4 - Faulty ignition coil 4 - Fuel injector 4 harness is open or shorted - Fuel injector 4 circuit poor electrical connection - Ignition coil 4 harness is open or shorted - Ignition coil 4 circuit poor electrical connection - Insufficient cylinder 4 compression - Incorrect fuel pressure - Intake air leak
