The IMRC is a pcm controlled butterfly valve in the intake that the imrc control keeps closed below 3k rpm's to help increase low end torque. The valves are built into the intake where it bolts to the head and has a motor mounted to the outside that move them depending on demand, this motor can become disconnected or not be able to move for some reason that will set a imrc dtc in the pcm. You will need to verify that the parts outside the intake are moving when commanded and if the valves inside the intake aren't sticking causing the motor to not be able to move them. All of the valves are attached to the same rod running from one side of the intake to the other with bushings between runners that can wear over time. If you look at the throttle body blade think of it 4 times attached to the same shaft in a row. Inspect, verify operation, then determine if it's the imrc actuator or the intake as the primary cause.
