In this video, I'm going to tried some fuel additives to get the check engine light to turn off due to P0420 code for Bank 1 Below Efficiency. Well the products I used did not work and I have to move to next option which will be possibly clean/replace the the O2 senor on the car. Let me know if this problem has accured in your Xterra and what the solution was.
