today I put a spark plug non fouler kit on certain downstream location on my car. So far it has seemed to stop a certain p0420 from showing up, but on the other hand it has changed my voltage reading on my downstream location. my question is for those who monitor reading with digital instrumentation, When in lean burn do you get a 0.000 reading on the downstream o2 sensor or some other number?
I was getting 0.000 prior to mod. now I get 1.555.
