This code indicates that the fuel/air mix entering the engine is too lean. A major cause of lean mixture is ingress of un-metered air into the inlet plenum. Check all vacuum lines, injection seals and the inlet plenum to cylinder head seals. If you suspect a leak, have the engine running and spray the affected area with WD40 spray. If there is a leak the engine will race for a moment as the flammable fluid penetrates and ignites.
