You'll need to get an oxygen sensor tool from AutoZone, and the recommended O2 sensors. Disconnect battery, then find the O2 sensor that you are replacing. Follow the wire back to the front bank of the engine. Unplug the connection. Remove the O2 sensor just like a spark plug. Replace, then attach the new wire as necessary. Plug it back in, and reconnect the battery. You should be set and ready to go.
