If you have the car computer scanned, which many auto parts stores will do free of charge, you will be able to retrieve a code that can point you in the excact direction of the problem. Without being there myself, the only thing I can say to try that I did not see mentioned is to check the fuel injector on the #4 cylinder. They sell a tool called a noid light, you can disconnect the injector and connect this tool to the wires to see if you are getting an injector pulse. If you are getting a pulse then you may have a bad fuel injector.
Please remember to rate this solution.

Check the gap setting on plugs. Also change the O2 sensor. This is usually the check engine light, or EGR-valve. You could also change it too. Then pull positive battery post off for a minute. THis should reset the computer.
