Just an update
Cleaned both the TB & ERG, replaced TB gasket and retested it
and only pulled codes for the shot o2sensor.
Where is the upper o2sensors on the contour?
My is a 2.5L Duratec V6 engine.
on most GM cars..the o2sensor was right under the battey housing
I'll like to do this myself, since it cost $450 to have it done at a Ford Dealership
