    Bad O2 Sensor?

    Hey, just want a second opinion - is this log showing a bad O2 sensor? No cats, all 4 O2 sensors are plugged in and should be working. Also have a video of it. 2023 Mach 1 w/ Whipple Stage 2. Idle is acting really weird, bouncing between like 790 and 860 or so. Also have a YT video: https://www.youtube.com/watch?v=3t-4NbOc6X0
