An internal combustion engine idle speed control system includes a first valve control mechanism that adjusts a first operating parameter of a first cylinder valve. A control module determines an idle speed error and generates a first control signal to the first valve control mechanism to adjust the first operating parameter. The first control signal is based on the idle speed error.
