Default After STFA......

looks like several people had O2 sensors replaced under CPO.

Could it have been the 109 octane?

Default Thanks Mark, work has me swamped like hell now so I didn't really have time to STFA

teach me to take two days off.

Nah, I've seen the O2 sensor code before, back when I was having all those issues with the Tip Chip/TCU.
But I'm wondering if the other codes I got, 17584 and 17585 which are the Bank1 and Bank2 O2 (Lambda) Correction Behind Catalyst: Control Limit Reached, is due to the 2.5 gallons of 109. But that really should have just made the total gas about 94 octane when mixed with the 91 already in the tank.

Might give the dealer a call about it.
