Scanmaster O2 #

[bdogge23]

When I am at idle or WOT, the O2#s bounce around from 050 to over 800. Is this normal? It never stabilizes to give me steady numbers.

Perfectly normal at idle, the millivolts change constantly. At WOT the reading should be in the high 700's to over 800. Any spark knock showing? - Jimmy

On the thin line.... a little lean.... fatten it up a bit just for safety sake. The alky is keeping it from knocking...

No knock showing. I didn't know if that was an indicator that the O2 sensor was going. Its sshowing mostly high 700s to low 800s at WOT but it still bounces down as low as 100 even during WOT
