with scangaugeII in the OBDII
Bank 1 Sensor 2, OX2 reads "127" if not mistaken on startup and in the manual car I have and in time drops to "0 " in lean burn, which I believe the CVT doesn't feature, so I hope that's not just spurious or your that CVT maps are way different.
Bank 1 Sensor 1, OX1, when cruising on the highway in lean burn reads "50" with the scangauge. I don't monitor it much because I'm mostly focused on lean burn and %load.
On idle speed after a hot day's run, the bank 1 sensor 2 read 7 at idle with intake air at 43 Celsius and held that for several minutes prior to shutdown.
In my own vehicle when the nitrogen purge happens, with the rocking out of lean burn into enrichment, the OX2 [Bank 1 Sensor 2] sensor goes directly up to 86 or 87.
First thing I'd do would be to check grounds and connections, and given the age of the O2 sensor, though it seems early, it would be the first part i'd throw at it.
Exhaust or gasket leaks in the exhaust??
MAP sensor dirty??? With the rough idle, if not a bad battery system with the IMA not counterbalancing electronically the three cylinder ICE's pulses I'd look there too. Best luck, I hope it's not something like rings.
