Code P0133

Code P0133
Ok, had to replace a bunch of failing items: MAF, throttle body, and clogged catalytic converter where it had been running rich with an erratic idle.
Now I have code P0133 which comes back as a slow response front O2 sensor. As luck would have it, I had a replacement on hand and put it in. Did the 20 time brake pedal stomp and....code/CEL still there.
Looking for ideas? Maybe drive a few times and see if it goes away?
The car certainly runs better now than it did before but I can still feel that lean running hesitation.

The engine was running rich because it was a rebuild and breaking in. Ignition was brand new OEM coils. Not running rich now. The cat was definitely done and I could smell it. My device is just a cell phone GPS device that plugs into the OBDII port and reads codes, not clears them.
