Code says "running Lean"

(1999 Ford Contour)
in Willow Street, PA on October 12, 2009
Changed plugs, wires, air filter, O2 sensor and oil. Cleared code but after a short run down the highway the check engine light came back on. I've checked vaccuum lines. Ran injector cleaner. No change. What next?

If all of your vacuum lines are good and connected properly you are left down to two things. Either you have a bad gasket somewhere in the induction system (throttle plate, intake manifold gaskets, cracked manifold etc.) Or you have a weak, or failed fuel injector. Please post your code, and we can take it further
