What would a person look for should this happen? I do see this as a way to get things "close" before a pull or running down a track for plug reading. Your input is appreciated.
What happens when you get a lean miss????? What do you think the O2 sensor will say?
That’s one quick example of how an O2 sensor can lie to you. It’s a dumb tool. It can’t think. You have to think for it and not take everything it says as gospel.
Also, you can run into reversion issues which will make the O2 sensor tell you fibs.
