A method and control system for controlling the idle speed of an engine includes an engine speed module that generates an engine speed signal. The control system also includes an actuator control module that regulates an engine speed based on a desired idle speed when an engine idle mode is enabled and a balancing module that balances torque produced by cylinders of an engine based on the engine speed signal when the engine idle mode is enabled. The control module also includes an idle speed reduction module that determines an idle speed reduction based on the actual torques produced by the cylinders after the balancing module balances the torque and that decreases the desired idle speed based on the idle speed reduction.
