Too bad you did not fix the oxygen sensor as soon as you knew it was bad. It does a lot for your car.
You have opened Pandora's box.
Running rich can cause any number of issues.
Our bricks can compensate for many problems, then they give up. Many years ago, I had a new Mass Air Sensor replaced and the tech told me that it may take as many as 12 trips for the car to get the best from the new sensor.
I have used the same dealer for more than 20 years and almost 600 K miles, and I have never had to replace or repair more than one part when one of our Volvos had a problem.
Good luck - getting out of your fix will be a much bigger job than replacing one bad part.
