.020 Over
i did turn power on while the O2 sensor wires were not conected and the dynojet plug was not on. but i did not notice the light when i first started iguss i could have missed it though. i was mostly watching computer screen. can i clear the code and see if it pops it again? or do i have to buy a scanner code reader to clear codes ? also i had it hooked to a car battery with a trickle charger on, voltage did not dip below 12.7 the hole time she was hooked up. everything seemed to be great
