It means the engine is running lean. A common cause of this is unmetered air entering the system. Check for vacuum leaks or a leak in your intake system. I'm not an expert in this area, but other members should chime in tomorrow morning with more help.

Try cleaning the mass air flow sensor.

My wifes GP did that, ended up being a vacuum leak. It was the rubber piece on the throttle body, a big hose and small hose run into it, got one at a junkyard. They seem to get brittle and crack easily.
