Running o2 CEL all of a sudden, WTF?

Happened to me 2x today; both times after driving the car for over an hour at a time. My A/F guage is still working properly. It happened both times while going a steady 50-55mph; and the ECU resets itself after I turn the car off/on... Bad o2, or WTF is going on? I though bad o2, but my A/F guage is still working fine, even after it throws the CEL.

BTW, how do you know your AF gague is even giving you accurate info??

Bad O2 IMO.

borrow a friends and see if you still get the CEL. I've found Honda ECUs are seldom wrong.
