I was running data logs last night, and I noticed something a bit odd (to me anyway). When I was at idle, or neutral, my O2 readings were showing fluxuation between .50 to .60 volts.

Is this normal? I would think that is a bit rich for idle. I get the same readings when I am at cruise speeds, which I would think is normal.

Thoughts, opinions, comments please.

Thanks,
Nathan
