where is the second 02 sensor before the cat on a 2.8 30v? I found the one under the engine coolant
tank on the driver's side. Any idea where the second one is? I STFA but no luck

I don't know of any car with two O2 sensors before the cat.....
so if you find one, let me know! :-D
The 2.8 engines have 4 O2 sensors, 2 pre-cat sensors, and 2 post cat sensors. You've found the pre-cat sensor for the driver's side(bank 2) under the coolant reservoir. the post cat for bank 2 is under the car, after the cat. Mirror'd images for the passenger side(bank 1).
