I used to get that code all the time when I had exhaust manifold leaks. Air enters upstream of the o2, ecm thinks engine is lean, richens to compensate, richens beyond acceptible limits then goes into "limp" mode because it knows a problem is present. May not be your 02 sensor. Although this is how it worked for me, may not be your situaton. fyi my engine always ran fine, no bogging during this, just a cel light.
