Any help/suggestions would be much appreciated!
Thanx again guys/gals!
Yes! That is the one. I have not changed this one myself, but from looking... It should not be too hard if you remove the coil pack.
Duratec has 4 02 sensors. One before the each precat and one after each precat. Precats are located inside the exhaust manifolds, of course.
