a lot of times it's something happening upstream of the sensors that is causing the sensor to get bad readings. The fact that it's getting readings and reporting the inconsistency is proof that the o2 is working properly.

I, too, have never seen all of them fail at one time...

I only got one "my bad" of taking car straight to Indy without letting the board take a peek at my codes first.

Any time something "isn't right" with my car now, it's "to the boards!"

Mechanics (and often the chevy/ford guys for some reason) seem to want to throw o2 sensors at every engine problem... i dunno why.. but it's annoying.
