Hi there. Getting to the O2 sensors are tricky without removing some additional components or using specialty tools. You might want to have a professional mobile mechanic come to your location and complete an O2 sensor replacement to help you. However, in many cases, what is commonly diagnosed as an O2 sensor problem is actually the electrical harness that connects the sensor to the ECU or other component. It might be best to replace the harness and sensor.
