A P0505 DTC, you will usually find a bad IAC or dirty throttle blade not closing all the way, try cleaning the throttle plate

Most likely its the idle air control valve. My mechanic is actually replacing mine tomorow. When its bad you'll get idling problems and bad gas mileage and probably weak performance. Also I had the same trouble code.
