The P0300's 301,302, and 303 are faulty coils codes #1,2 & 3 respectively. So it's ignition/coil related, the other ones are O2 sensor related. Backfiring through the engine might be timing related. I'll let others respond to give you some more information and help on where to start.

The misfire codes are all for bank 1. Have you had the spark plug wires off recently? sounds like they could be installed wrong on that bank.

yes i just replaced the wires and plugs

Make sure they are on correctly. They are labeled on the coil. And cylinders #1,2 and 3 go in order starting with the first one on the right hand side

would any of this stop it from runing?

Yes. If they are on wrong it is not firing the right plug at the right time.

yes

Misfiring causes it not to burn all the fuel in the cyl. And it stays on the plug

i checked the wires and they are all on right.

Maybe the ignition coil its self is bad. Never seen one kill one whole bank but ya never know

Im getting fire at the coil,but im going to try another one. I wish i could find someone to check my whole motor over.
