1994 Skylar 2.3 liter 02 Sensor problem

Hi,

I have a 1994 skylark with a 2.3 liter engine.

The check engine light comes on and I pulled the codes up and it said 02 sensor is short or open. The car runs perfect until the check engine light comes on , then it gets boggy and dont run very well.
I replaced the 02 sensor and it still comes up after clearing the code.
Any Ideas any one.
Thanks,

I've had the same problem, sort of. Every sence i have put a new o2 sensor in my 95 skylark, My car has not been able to idle right
