Oxygen Sensor

Your going to need an oxygen sensor installation tool, when u purchase your sensor u can purchase the tool also, the tool runs about $15.00 i'd get a manual as well as a guide for u. But first u must determine if u have one or two sensors, my car has 2, an outer and an inner because I have 2 catalytic convertors. Again get a manual to guide u along. If u have 2 sensors, that can be costly. I replaced mine, and the both of them totalled $250.00
