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
