Look for vacume hose that could be split or disconnected. From that point it could be caused by various faulty sensors, wiring problem, or a mechanical problem. Driving with a lean condition for extended period could leed to more problems.

I have the same problem with mine. "too lean" I've tried getting the O2 senor replaced, but no luck.
