The P0440 is an EVAP malfunction code. The P1507 is manufacturer specific which you wouldn't be able to figure out without taking it to Subaru and the P0500 is for vehicle speed sensor malfunction. The misfire could either be due to a vacuum leak, faulty injector, ability spark plugs, spark plug wires or ignition coil pack.
