Tried a search, found nada. Not sure if our 3.0's have one or two o2 sensors, but just curious if anyone could point me in the right direction to locate them since I have new ones that want to install. Any diagrams or just general description would be greatly appreciated. Thanks

Your car has two 02 sensors. One before the catalytic converter, and one after. Look closer... its there :P

The 3.0 is an ODB2 car so it has 2 o2 sensors. One before the CAT and one after the CAT. Check your headers for the primary heated o2 sensor location, and check ontop of the cat for the secondary o2 sensor. Haven't replaced one so idk where the wires run to and what not, doing that soon too though. Go rent or buy an O2 socket and have at it They're a pain to remove usually... took me a crescent wrench, a hammer, and the CAT heat shield to get mine off the first time lol

I think you need to be under the car, at least for the one by the cat

thanks for all the replies guys....but....bad news

took off the header shield today, and found the front o2 sensor absolutely nowhere. I know they're typically on most hondas-acuras directly on the front or side of the header piping, but not the case on the 3.0's. Has anyone replaced theirs? I'm thinking maybe they're both in the rear subcarriage near the cat?
