new 02 from Bosch

[97gpl36]

Sorry if i'm posting in the wrong forum,but how does a guy supposed to feel when he buys a new 02S1,and the damn thing sits on 483mv from the start? 58*-198*,
does not matter,stft @ 20 with ltft not far behind. Maybe this should have went to the rant forum.Anyone else had problems running Bosch 02 sensors? No rich to lean changes either.

they are junk. Stick with delco oem replacments. It'll fix all your problems

I have a denso but i've heard they aren't much better.
