There are about 20 different 0/2 codes. None of them indicate a bad 0/2 sensor.
All you accomplish by disconnecting the battery is to erase all the valuable information the computer has stored concerning the failures.
Now you need to drive it long enough for the check engine light to come back on. Then read the codes and post the numbers here.
In the meantime
First eliminate all vacuum or air leaks in the system (very important)
. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
