O2 sensor readings all over the place

[hoycoconut]

Just got my Pocketlogger

My A/F guage bounces around like mad and now according to the logger so is my Bank 1 O2 sensor voltage. The graph from a trip around the block looks like this

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

well more jaggie than that. I assume that is abnormal. I threw my CEL with a bad heater circuit on that sensor and have one in the mail, just wondering what to expect when I put the new one in.

Thanks

If you were just driving around normally then yes your O2's will be all over the place, that's normal.

They don't steady out untill you go WOT then there should read somewhere around .94v
