What should be my target o2 voltage from my sensors? I'm most recent readings were about 875

 

That sounds lean. Is this a WB O² or a stock unit?

 

Ack vader your right so often. Howd you miss an easy one?

.450 is stociometry(perfect)
Higher numbers result from a greater difference in o2 inside and outside the exhaust. No o2 in the exhaust is a rich condition and thats what you have.

 

DOH! (Brain not fully enganged) Low oxygen - Rich... Sorry. Slap me and I might wake up.
