Oxygen Sensor on 2002 Mitsubishi Eclipse

can i Change Oxygen Sensor myself?

Asked by for the 2002 Mitsubishi Eclipse
Unless you have some experience, I don't recommend it. The oxygen sensors, and your car has more than one, are part of the very sensitive emission control system on your car, and if you do not know all of the different components to check and have some diagnostic expertise, then it is best to go to a pro.
