and what is the imrc?!



Read the links posted previously. Intake Manifold Runner Control. Supposed to control the secondary butterfly valves. Opens when it is above 3,500 to 4,000 RPM so that more air can go into the engine. If the secondaries are stuck closed, you will experience a "no power feeling" above those RPMs.
