I am not sure how many miles you have on this engine, but I would check all of the vacuum elbows and lines for leaks. Especially the one that goes around the engine on the passenger side. A vacuum leak causes the system to run rich and the O2 sensors object.
If you have over 150K miles, I would replace both sensors with original Bosh.
