A feedforward throttle adjustment for a closed loop idle speed control provides engine power output required to drive a variable power steering load while maintaining the engine idle speed in a desired range. The working pressure of the power steering system is detected, and the change in such pressure in the course of a steering maneuver is used to initiate an increase in the engine power output setting. The increase is determined in relation to the peak pressure change; it is implemented at a pedetermined rate, and is subject to interruption whenever the pressure change indicates that the steering maneuver has ended.
