318 - 222 = 96
It doesn't have one.
In my '96 K2500 it is between the exhaust manifold and the catalytic converter.
It has an altitude of 318 feet or 96 meters.
It's under the intake manifold, between the engine and the firewall. 2 bolts, and you have to get to it from underneath the car.
The 1996 Mercury Gran Marquis does not have a 318 V8. It has a 281 V8 (4.6 Liter). 318 is a Chrysler engine. O2 sensors are located screwed into the exhaust system. Start at the exhaust manifold and go backward and you will find them. The cost varies from site to site. Ask you local Auto Parts store for a price quote.
It is under the intake manifold.

The knock sensor is on top of the engine block between the heads under the intake manifold and the coolant pipes.
