How does ur stock o2 behave under overrich conditions?

[ittybittyt25]

I'd like to get insight on those who have experienced an overrich setup and monitored their stock o2's behavior. What kind of voltages did u see? ie. were they high .90's? did they read some totally outrageous number? I'd love some feedback on people's experiences

if you are running really rich you will see high .90 numbers on the o2 reading. that is until it reads 0 cause its fried.

after rewireing my stock fuel pump I see .94-.96's all across the board. The car runs better and my o2's are far more consistant.
