Default Re: 96 civic ex O2 sensor

O2's can do some funky things in that respect but if your post cat o2 simply isn't there your probably in open loop in which the ecu isn't looking at the o2 sensors for feedback. So if your having an off idle hesitation your best bet is to look somewhere else. Hope that helps. Gl
