Clean and test the electronic idle air control valve and the throttle angle sensor-

Ensure the coolant level is correct. Low coolant level or clogged hoses to the IAC and Fast Idle Thermal valve would have same efffect. Ensure thermostat is not staying in open position.

Check the power steering fluid condition and level. Replace the fluid if necessary and retest. If noise persists, the pump or pressure hose could be the cause of the noise.
