O2 Sensor question on a 95 SHO

I just want to know how many Oxigen sensors the 1995 SHO has. I heard that it has 2 and I heard 4. Can somebody clarify this for me? I replaced 2 of them going down the maniford but if there is a total of 4, I need to replace 2 more and I have no clue where they are.

Please advise.

Your model year is one of those borderline years. It probably has 2, but could have 3, and might have 4. I don't believe the Taurus started the transition to OBD-2 compliance in 1995 like a few other Fords, so I would guess you just have two.

If you have more than 2, the others will be just after the catalytic converter. If I recall correctly, the SHO does not have true dual exhaust, so it may have a y-pipe, then catalytic converter followed by one sensor post-cat, then split back to two tail pipes. If there are two catalytic converters, one for each bank of cylinders, there may be one sensor after each converter as well as the two you likely already found before the converters.
