Wait, so I just enabled the O2 bank 2 sensor on my UG and I noticed my Corolla will drop down to 0.150, does that mean the Corolla is capable of leaning out as well at low speed...?
Anyway, I noticed the civic, when cruising around 55mph and light load will drop to 0.035-0.050 which isn't lean burn but meh... It seems extremely hard to get it to drop into L/B... I'm guessing it's the really long time it hasn't been serviced is the reason it won't. I'm hoping that once I get the timing belt job done, new spark plugs/wires/oil it will help it a lot.
