Answer 1

P0300 Random misfire

P0481 Cooling fan control1 relay circuit malfunction.

Is not overheating is it? For random misfire you need to check fuel pressure,Check for vacuum leaks,also the charging system , battery 12.5  or more with engine and accesorries off. When running charging will produce 2 volts above battery you should see 14 volts. As for P0481 this is fan control relay,inspect fuse 22 which is a 40amp fuse and fuse 19 which is a 50 amp fuse.if good you may need relays or fan control module
