Ok, i know that an o2 sensor is supposed to sweep from 0-1 volt in closed loop.

Is it supposed to still sweep regardless of whether the engine is running lean or rich?

Im having a misfire issue at idle and noticed that when it starts missing, the o2 stays pegged at 0 volts. My afr goes full lean as well. Its not a constant misfire either, just a hiccup if you will.
