[QUOTE="BigPoppa, post: 16462447, member: 177587"] Upstream will always read lean. Downstream will normally read rich since the cat uses up the O2 to catalyze the unburned HC (if you have cats....otherwise, they will read lean without cats as well). It will confuse the hell out of you if you don't keep in mind that the sensors always read O2 only, not air to fuel ratio..... [/QUOTE]
