Here's some info for you...

What code are you getting?

perhaps its just the whole o2 sensor.... i mean its on the exhaust all by its self....

If you're getting a code on the 02 heater, you're going to have to replace the 02 sensor.

Four-wire 02 sensors have a built-in heater to heat the sensor up when the car is first started. It's common for those to go bad.

Thanks for the info Marvinmycat. I had a short in the wiring at the O2 connector. Also thanks for the rest that gave me some feed back.
