At ilde in stalls when you turn the steering wheel any direction?

There is a sensor on the power steering pressure hose that tells the ECM when the pressure increases which is an indication that you are turning the wheel. When the pressure goes up the ECM automatically increases the idle speed to compensate. If the pressure sensor fails then the ECM doesn't know you turned the wheels so it doesn't boost the idle speed and the engine may stall. So check the power steering pressure sensor.
