Another bad o2 sensor. What part#??

Cool, thanks

I am very conflicted. I ordered the sensor, but... i am not 100% mine is bad... i have been monitoring it in the torque app, both bank 1 and bank 2 sensor and they both seem to be working just fine...

If the sensor is bad like mine the AF should fluctuate from rich to lean constantly and never settle at stoich
