My exhaust O2 sensor is causing check engine lights, indicating my CAT(s) are not working as well as they did back when the truck was new. Unfortunately I can't afford to replace them right now, and I can't get an inspection sticker with a check engine light on. Thus, I'm thinking about this washer hack. Apparently you put a washer in before you screw in the sensor and it senses less.
Has anyone done this before? How easy is it? How thick a washer (or stack) do you need? My local hardware store has a great selection of stainless steel washers, will my truck run with one of hte sensors completely removed so I can bring it in and see what fits best?
