If you open your hood and look at your engine, below you will see the exhaust with an aluminum plate covering it. There will be an o2 sensor that screws into a hole in the exhaust with wires coming out of the end of it. When you take the sensor out, it should be slightly blackened at the end. Just remove it and replace it with a new one.

Bank one is going to be the left bank "bank 1"on a Chevrolet and the emission system has O2 sensors and also monitor sensors which will be the "2". So either the sensor on the front of the engine after the catalytic converter is bad or it is sensing the cat is bad. You need to take your vehicle to a repair facility that has the capability of monitoring the sensors via computer to tell you if it is the sensor or the cat.

I need help, as far as locating them, and replacing them.

Thanks Mike... you have always been a big help.
