Yes - in my particular situation I’ve got my baseline CO set so my warm idle with O2 disconnected and air pump disconnected (pump is just blowing into engine compartment, line to ports plugged) so that AFR is 13.5. O2 sensor plugged back in so now it idles at 14.7.

My Big Question is -- So when I reconnect the air pump – won’t it throw everything off (at idle and low rpm) because its pumping raw air into the system pre-O2 sensor? Won’t it think the car is running lean and thus increase fuel – causing it to run rich in the cylinders but look normal at the O2 once the extra air is pumped in?????

I’m missing something somewhere as to how it all functions….

( Yes I know many just dump the whole system but I don't want to do that - for hassle factor and future emissions issues should I ever sell - so let's leave that solution out - thanks.)
