In a 2000 Ford Windstar SEL, the map sensor (Manifold Absolute Pressure sensor) is typically located on the intake manifold, near the throttle body. It is a small electrical component with a vacuum line attached to it, often mounted on the engine's upper intake. You may need to remove some components for easier access, but it should be relatively straightforward to locate.
Have the head gaskets checked and intake manifold gaskets checked for leaks. The 3.4's are known for head and intake leaks! Or a bad thermostat.
The 3.8 GM V6 is prone to blown intake gaskets much more than blown head gaskets. The blown intake gasket causes a loss of coolant which in turn causes overheating and a blown head gasket. The problem exists with most 2000 to 2003 vehicles equipped with the 3.8 Liter V6. There were defects in the upper intake manifold gasket, throttle body nuts, and the throttle body gasket.
Assuming this is a 4.3L engine, the upper intake manifold gasket would be between the upper intake manifold and the lower intake manifold.
The Intake Manifold Runner Control (IMRC) on a 2000 Ford Windstar is located on the intake manifold itself. It is typically positioned near the throttle body and is connected to the intake runners. The IMRC system helps optimize airflow for improved engine performance and efficiency. To access it, you may need to remove some components, such as the air intake duct or other nearby parts.
Remove the upper intake.
The EGR valve on a 2000 Ford Windstar is located on the intake manifold near the firewall. It is typically located to the left of the main throttle body or slightly lower than the throttle body. On the passenger side it is located on the side of the intake manifold closest to the firewall. On the driver side it is located on the side of the intake manifold closest to the engine.
It is hidden on the intake near where the upper radiator hose attaches.
The IAC valve is mounted on the upper intake plenum (manifold)

You have to remove the upper intake manifold.
