Put 02 sensors on my vehicle

Comstock Park MI

Description

Hi there. I have a 1996 Oldsmobile and need 02 sensors installed. Let me know if you have the special socket to do this. I know i dont have one. There are two sensors one called the upstream sensor and one called the downstream sensor. I can see the upstream sensor from under the hood. It looks easy to get to. Not sure about the downstream one yet.
