sprak plugs are indicating too rich...could it be because the o2 sensor is bad??..plugs says that engine is too rich but air fuel gauge says its lean...d16z6 into a 92 cx with a p28...i was thinking that i have to cahnge out to a 4 wire o2 sensor instead of the single wire the cx has...i already did a search and foudn out how to do so just need to know if its something i need to do?? thanx all

small tidbit for ya, p28's use a four wire sensor usually two black wires a white and a green so I would say before you do anything else go ahead and put the correct sensor in it and go from there. hope this helps
