What does the imrc control module do?

The IMRC (Intake Manifold Runner Control) module regulates the operation of the intake manifold runner valves in an engine. These valves adjust the airflow into the engine to optimize performance and efficiency across different RPM ranges. By altering the intake path, the IMRC enhances torque at lower speeds and improves overall engine responsiveness. Proper functioning of the IMRC is crucial for maintaining engine power and fuel efficiency.
