Steerin wheel effecting idle?

This is the weirdest thing i’ve seen my car doing. When the car is either parked idling normal, or in a traffic light in nuetral without stepping on the gas and it’s idling normal…but when you turn the steering wheel slightly to the left or to the right the idle goes up (increased at least 500rpm). Does anyone know anything about this? Thanks

possibly bad power steering pump and or low fluid? usually caused my cars to drop idle though…
