Actually, it sounds like the power steering pressure switch is WORKING,  and
that something else is buggering your idle. When the switch detects high
demand from the PS pump, it basically gooses the idle a bit via the idle
control valve. What happens to the idle when you unplug the connector from
the idle control valve?
