1-34 Description and Operation
Engine Control Components
The IMRC shutters are in the closed position below 3,000 RPM to create air flow turbulence for better charge mixing in the cylinder. The IMRC shutters are in the open position above 3,000 RPM to reduce air flow restriction.

Intake Manifold Tuning Valve (IMTV)
WARNING: Substantial opening and closing torque is applied by this system. To prevent injury, be careful to keep fingers away from lever mechanisms when actuated. Failure to follow these instructions may result in personal injury.
The IMTV is a motorized actuated unit mounted directly to the intake manifold. The IMTV actuator controls a shutter device attached to the actuator shaft. There is no monitor input to the PCM with this system to indicate shutter position.
