Hello and welcome to JustAnswer!

P2305 is for the number 2 ignition coil circuit and is related to it running poorly. It will take some electrical testing to determine exactly what is going on, the problem may be the coil itself, a wiring issue, or a failed coil driver within the powertrain control module. The coil itself or an open circuit in the wiring would be most common.

P0457 sets when the PCM perceives that the gas cap has been left loose and can be caused by actually leaving the cap loose, or if the cap hasn't been left loose then the most likely cause would be a bad evaporative system integrity monitor.

The other two codes listed are not valid.
