Thought I'd help some people out with the locations of the 4 O2 sensors
Bank 1 is passenger side as it goes with cyl 1
Bank 2 is drive side
2 on each Bank (Before and After Cats

The front sensor on the passenger side is a B***h to get to..
The sensors are a 7/8 wrench or they sell sensor specific tools.

Anybody else that has tips feel free to add

That is a great post with pics. People need to know though, that only the upstream sensors have the ability to "adjust" air/fuel ratios. The downstream just "monitor" but do not signal the PCM to make any adjustments. So in reality, you only need to ever make sure the 2 nearest the exhaust manifold on each side are in good working order.
