You didn't change the one behind the converter. There is an O2 sensor after your catalytic converter. It is underneath the truck. The O2 sensors that are underneath are exposed to a lot of road debris, water, elements etc. They usually go bad after a while. Try changing that one. I had the same problem on my 98 Grand Prix. The O2 sensor before the cat (the one you changed) is usually in a lot bet shape because it is under the hood. Try changing the one underneath and see what happens. Good luck.

What's the error code? What motor?
Lot's of things will make the O2 sensor give bad readings.
Could be a bad ground from the motor to the frame. Could be a bad sensor wire or connector. Could be a bad computer.
Need more info.

Sensor 2 should be the rear one.
