04 g35 help - p0300

[deuce90]

I have an 04 g35 giving me a few problems. It sounds horrible and has almost absolutely no acceleration. I know for a fact there is an exhaust leak/hole from the rusting which makes the car louder. The exhaust is making a loud popping noise because of the leak but i'm also getting two p0300 misfire codes. All the lights on the dash are on and I have done multiple ECU resets. She idles rough and won't really accelerate. Also, the spark plugs have just been changed. Any help would be greatly appreciated. Heeeeeeeeellllllllppppppp!
Ill try to get a video of the sound and acceleration tomorrow. Thanks in advance.

Here's a great resource for deciphering codes:

Check out the FSM (link in my sig) for more in-depth troubleshooting. I'd check all the ignition wires...sounds like a coil pack to me.
