but this could also be caused by an exhaust leak before (or near) the catalytic converter - check the easy stuff first.

A.I.R. pump not working can pop that code once and awhile . get a scan tool that can watch all 4 sensors at once . if you have alot of miles i would change all 4 . $ it hurts but only if that one is bad
