Code is Lambda Control 1, I had that one the other day. It was a vacuum line that had come off the fuel pressure regulator. Start checking for vacuum leaks under and around the intake.

The vacuum line to the fuel regulator has a tight kink to it and can often crack without it being noticable. Take off your fuel pressure regulator vacuum line and carefully check it for cracks.
