The intake manifold runner control is the little black cylinder on the back plenum of the engine, with two little vacuum hoses. It has a little electric solenoid right next to it with two wires attached to it. Check the wires, make sure they're still connected. Make sure the vacuum hoses are still connected.

Actually, that little black cylinder is not THE IMRC although it is part of the IMRC system (vacuum reservoir/check-valve).

The IMRC system includes that cylinder, the solenoid (check ITS connector/coil), the associated vacuum lines, and the two vacuum motors on the intake.
