thumbs up, i also think my o2 is sluggish. due to no MIL if it was bad then there should be MIL.
ill enable my obd to retrieve my post o2 readings later
it should read about the same. just to make sure.
if not ill diagnose my pre o2 n my ecu n hopefully it is not ECU or ill be crying LoL.
About the sensor as a noob tech. (me)
i certainly know if the o2 is reading 0v means lean , 1v means rich.
ive been fixing ppls cars for years and ive been looking for a job as entry lvl tech but noone want to hire me :'(
if im wrong about volt reading, maybe thats why shop owners dont want to hire me ;'(
anyway, thanks guys ill update the thread once i get everything fixed
feel free to leave suggestions and comments.

Anyway back to your car issue, the voltage on the o2 should cycle back between 200mv to 600mv rapidly at idle, if not it's lazy, probably a good idea to change it out.
