It is the intake air temperature sensor , and it,s located in the air intake boot.
It is under the intake manifold. Darn hard to get to and expensive to change.
The Villager has an upper and lower intake manifold. It is at the top of the engine with the throttle body attached to it.
The most likely cause is an intake manifold gasket leak (that is if all the hoses and water pump have been ruled out)
In a 1998 Mercury Villager, the mass air flow sensor is located in the air intake tube. The air intake tube goes from the air box to the intake.
Intake Air Temperature Sensor. Located in the plastic air intake tube beside the battery.
The knock sensor is under the intake manifold, which has to be removed. This should be left to an experienced mechanic.
Sitting right on top of the engine.
It is under the intake manifold.
On top of the engine. Everything between the valve covers is considered the intake manifold.

The Intake gasket is leaking, NOT THE HEAD GASKET. Replace the intake gasket
The 1999 Mercury Milliliter intake bolt torque specifications is 60 pounds per square inch. The intake bolts should be torqued at 30 pound intervals.
the knock sensor is under intake, must remove intake and it is under two coolant lines.
Pretty straight forward. You must remove the intake manifold in order to replace the gasket.
i asked the question how would i know the answer
You can get that at the library in one of the Automotive Repair Books dealing with Mercury Villagers. I think you mean Vacuum Hose Diagram anyways.
