I have ordered a O2 sensor, but I am going to swap the stock sensors to trouble shoot and see if the code goes to the bank 1 side to see if possibly the sensor went bad. Still new to this stuff so forgive me if I sound amateur about this. Just trying to get some advice on how to get rid of this engine code before emissions.
Any input would be greatly appreciated!
Thank you.

Is the car completely stock…?
