Questions Code P0263

While driving home the other night, my 2010 F250 kind of sputtered and loss a little bit of power then went smooth again. I got home and ran diagnostic on it. It put up the code P0263 Ive read a few different things about it and am a little confused about what all I need to do. I cleared the code off of it and drove it the next day. Im from Oklahoma and the weather got into the negatives the other night then is back up to the 50s, I know classic Oklahoma weather. Anyways I drove it and didn't really notice any sputtering or loss of power. I dont drive the truck much on the weekends due to my job. Im just looking for advice on what I can do or if this is a major problem I need to be concerned of. Any Help PLEASE!!!!!
