Well today I got my Ultra Gauge and I love it , it really teaches you how to drive well I been having some problems with my car with MPG I replaced both O2 sensors last week now that I have my Ultra gauge this is what it reads on both o2 sensors
Bank 1 o2 1. 0.780 volts at idle
Bank 1 o2 2. 1.275 volts at idle and this one is stuck there
Is this normal for the second o2 sensor to read this and be stuck there

Front should be switching rapidly between .1 and .9, rear one should be following along but dampened and lessened as if it were the exact same meter with molasses poured on it. 1.275 means it isn't getting hot enough to switch on.

That's good to know. I have the same O2 readings on mine, however, the #2 does not warm up and work, hence the P0420 code.
