Run a bottle of fuel injector cleaner(Techron is highly regarded,
comes in constant use and one-shot strengths), check for vacuum
leaks...and make sure the car is thoroughly warmed up before the test.

Are you up to date on all the regular maintenance items?
Plugs/wires/cap/rotor, fuel+air filter, etc?  No guarantees, but
every little bit helps.

Pull the fuse for the ECU after you change the O2 sensor, and give it
at least a day or two of driving to adapt.
