More information would be very helpful....
what engine?
which 02 sensor?
why did you replace it in the 1st place..what was the original symptom?
did the problem get worse after installing the 02 sensor?

Id recommend reading the codes if you havent already.
Check for vacuum leaks and check fuel pressure.
Report back with what you find.
