I think that one means you are running lean...most likely has to do with a crack in the intake boot behind the MAF sensor, but could be something else with the intake. Odbii codes are universal and don't pinpoint specific failures. Also if it is the intake, after replacement you will have to clear the won't go away automatically.

Any other symptoms, noises or other codes?
