How do you replace the o2 sensor? The engine light is continuously on, and I think that is what it is. I tried to have it checked at Auto Zone, but I couldn't find the box to put the reader in after taking off the plastic covering and all of that good stuff. Of course, they wouldn't look for me.

I'm not a mechanic or anything so I wouldn't have any idea on how to do that.

I understand-bring it in the MIL coming On -It means the computer has identified a problem within the engine management system code/s has to be pulled to get to the problem. This is your starting point.
