It sounds like the fuel is not being delivered sufficently to the engine. Try looking here. Perhaps a fuel injecter cleaner (you can pour Seafoam into the gas tank and it is a great fuel injecter cleaner and fuel stabilizer). What did your plugs look like when you replaced them? This can tell you a lot about the combustion chamber. A Haynes manual will be invaluable to you.

Still need the codes.
Injectors can go "bad" in a couple of different ways; all they are is an electromagneticaly controlled nozzle. When the ECU "fires" the injector, it pulses a ground circuit for 4-8 milliseconds, the electromagnet powers up, the valve at the bottom of the injector opens, and the fuel shoots out, under pressure. The wire can be bad/chafed/corodded/ The electromagnet may be weak. The nozzle may be stuck. Lots of things. But, to put in an injector for a number 4 cylinder misfire (p-0304 code) would be one of the last things that I would do.

That code is a Throttle Position Malfunction code.
This means one of two things:
1. The throttle body needs replaced
2. After the dead battery, you need to adapt the the throttle body.
The cheap way to do this is to leave the driver's door open, turn the key to the on position, but do not start the car. You will hear the throttle body self-adjust. This may take up to 2 minutes. That should get it close enough. To get it perfect requires a trip to the dealership.
If it does not help, the throttle body might be dead.

if you have a no spark scenario i would check your crank sensor located at the top left side of the harmonic balance pulley.the crankshaft (about 11'oclock) a 2 wire plug with a sensor on it check to see if it is damaged or unsecured. this sensor can cause no spark if not working correctly. This sensor is based of frequency not voltage testing is difficult, just make sure that there isnt too muck air gap. and that it is secured.Lastly may want to check timing possible that the belt has jumped some teeth and she has fallen out of timing. maybe a bad tensioner The coil will adapt i think up to 10 degree, ****** or advance. Good luck
