How many o2 sensors are in a 2002 mitsubishi eclipse? GT v6 3.0. How many are upstream and how many downstream? I thought 2 of each... I think I found another one?

Hmmm . . .

You should have an upstream (pre-cat) and a downstream (post-cat) O2 sensor for each cylinder bank. I can't find a reference to any more than that.
