Sounds like you have a vacuum leak somewhere. On my Supra it would do something similar when I would blow off the piping off the throttle body. If there was a problem with the 02 sensor the engine would probably go into "limp" mode and would run rich. Are you positive you bought the right 02 sensor? They are different based on year, California car, and transmission.

i was very sure to make sure my 4runner was not a California car.
