Question What do you think about these O2 readings?

This is from an AutoTap log, at idle only..... What are you thoughts about the Bank 1 sensor?

I haven't switched the sensors to opposite sides, but I found it odd that it was reading a value, just not varying like normal. Also, this has caused the LTFT for bank 1 to hit max of +25%
