Assuming this is fuel injected system, look for where the air filter hose goes into the intake manifold entrance (goes from rubber to metal). Remove the hose from the intake entrance. The intake entrance is where the cable from the gas pedal meets the intake at a device that opens the first butterfly valve. Remove the four screws that retain the throttle control section and disconnect the wires to the throttle position sensor and the idle intake control valve. The IMRC is now exposed below the intake throttle valve section. It will come off after removing the two top screws and one at the bottom. It is likely a sealed unit and not serviceable.
