Does anyone have a diagram showinng me where the bank one sensor 2 o2 sensor is on a 1999 Max. I was considering doing the repair myself, and would appreciate any tips, or suggestions.

 

If you have federal emissions like I do, theres 2 O2 sensors in the front on the two collectors on the ypipe. The back on is like after the cat I beleive. They arent very easy to get to if you have your stock ypipe on, you might want to unbolt the whole ypipe to get to them. I just know theres limited room to work with under there with the stock ypipe, precats take up a sh!tload of room.
