02 sensor 92 sts

After replacing both my O2 sensors, I am still getting the code coming up saying my right sensor is the problem. , which in turn is making the car run rich (black smoke) and the check engine light comes on. Any suggestions- bad ground or..?

You may have a leaking fuel injector. Remove the fuel rail and injectors and turn the ignition to the ON position and watch the injectors. There should not be any leaking fuel from the injector tips.

If any are leaking, you can either replace the leaking injectors or have your existing ones cleaned and rebuilt.
