I am having an idle problem. When looking at the numbers at idle on the YDS monitor page the O2 sensor reading is at .02 V. If I put it in gear and raise the rpms to about 1,000, it will rise to about .3 V. This reading at idle indicates a super lean condition right? Fuel pressures look normal and the #1 plug was wet when I took it out. The O2 sensor reading stays pretty constant and does not jump around like some say it should. I cleaned the sensor about 3 months ago. Could I have damaged it? It had a ton of carbon on it.
