Either your cat is bad(unlikely) or your downstream sensor is getting lazy(likely). Replace the sensor and you should be good to go.

Just don't buy Bosch O2 sensors. The Bonnys don't like them. BTDT. I only posted this since you mentioned Autozone and around here, the Bosch is all they stock for my 01 SSEI.

I completely agree! AC delco or Delphi is the only way to go on engine management parts. My local napa carries a lot of Delphi stuff.
