Error Codes P0305 / 2315

[ozone405]

over a week ago driving home my car started pulling a little and a rough idle. I took it to autozone and had them pull codes P2314 and P0305 (cylinder 5 misfire and ignition coil). Took it to a mechanic and they said my spark plug was bad and "off". Drove it later and the same codes and engine light came back on. The next day i got the ignition coil changed. Drove it later on that day and same same codes and engine light came back on. They said my fuel injectors are good, what else could this possibly be? i have 46K on a 2013 Dodge Charger SXT

If your plugs have never been changed do that, check wiring to the coil, then run high octane gas through your car. Should have swapped coils first, would have saved you some coin.
