IMRC stands for intake manifold runner controller. It is used for emission control and performance. your intake manifold has plates inside that are connected to a rod and tghe connected to the control motor. each bank of the engine can be opened and closed by the motor depending on engine load and other things. If the motor gets burns out or is shorted internally it will neend to be replaced. also the rods that go from the motor to the intake can come off at the intake or at the motor. if this happens the bushings will need to be replaced.

Its under the front valve vanity cover.
on the front side of the lower manifold
Since you are asking, I assume you have a V6 Duratec powered contour. If this is the case, the IMRC is located just in front of the engine, underneath the IMRC cover, the plastic cover mounted to the engine with several screws and says "Duratec" on it.
its under the plastic manifold cover with duratec v6 on it,
The intake manifold runner control (IMRC) is beneath the plastic IMRC cover, which is held on by several screws.
Intake manifold runner control aka imrc valve
The IMRC is held in a metal box in front of the engine. It is covered by the plastic thing, called the IMRC cover by ford. There should be three or four bolts holding the cover on.
Engine code P1518 on a 2001 Ford Windstar indicates a problem with the intake manifold runner control (IMRC) system. This code typically suggests that the IMRC does not respond as expected, which can lead to poor engine performance and reduced fuel efficiency. Possible causes include a malfunctioning IMRC actuator, a faulty sensor, or issues with the wiring or connectors. It's advisable to inspect these components to diagnose and resolve the issue effectively.
To replace the IMRC actuator on a 2000 Ford Windstar, first disconnect the negative battery cable for safety. Then, remove the intake manifold by disconnecting the necessary components, such as the throttle body and vacuum lines, to access the IMRC actuator. Unplug the electrical connector and remove the mounting bolts holding the actuator in place. Install the new actuator by reversing the steps, ensuring everything is reconnected properly before reattaching the battery cable.

You may want to check the IMRC's which control fuel flow on the intakes. These went bad on my 97.
