456 Power steering question (s)

I have two (2) 456 cars, and they both have the same symptons:

When the RPM is at or near idle,
and the throttle closed,
when turning the car behaves
as if the power steering is a little "off."

This manifests itself as a "jerky" or "knotchy" feeling at the wheel,
and the power steering acting "sluggish."

Among other things, I am wondering if I am soon looking
for power steering pump(s),
or whether the pump is
just "underboosted" at low RPM.

Has anybody else noticed this situation ?

Anybody had to do repairs ?

Thanks in advance,
