Where is manifold runner control located on a 97 ford 4.2?

On a 1997 Ford 4.2L engine, the manifold runner control (MRC) is typically located on the intake manifold. It is part of the variable intake system, which helps optimize engine performance by adjusting the airflow based on engine speed and load. The control mechanism is usually connected to an actuator that alters the position of the intake runners. For access, you may need to remove various components, including the throttle body or air intake ductwork.
