Thankyou, you are correct, it is .6% +- .2%. It is currently set at 2%. I'll tweek from there to see where it runs best. What effect will leaving the O2 sensor permanently disconnected (other than poor gas mileage) be on setting the CO outside of spec? I no longer have the cat so I am wondering if I can leave the O2 disconnected.
