O2 sensor

[Mholian220]

My explorer needs a new o2 sensor, I would like to install it myself to save some money, any suggestions on how to rePlace it?

Welcome to the forum! There is a wide selection of how to's. The Oxygen sensor is probably one of the easier things you can do besides a light bulb. It will require a special oxygen sensor socket so you can remove the old one without damaging the plug as well as install the new plug.
