i've been driving around for 3k miles (99 accord 2.3l)...since i change my spark plugs I put a gap of .44mm, cause that was what I assumed... (civics, integra) . Does it mean because of the smaller gap, I probably was burning richer that normal? I wonder if this have anything to do with my CEL (o2 sensor high voltage) .. high voltage because it senses burning rich
