Very High Idle ISV Problem

[Christopher Flanner]

Please help me to get some basic ISV understanding.  The engine is an MC
from an '86 5ktq.  A spring keeps the ISV closed when unpowered.  Does the
solenoid help to keep the valve closed when powered or does it help to keep
it open (I know it varies in a range)?  I assumed the valve stays closed by
itself since I've heard of people disconnecting it and having an acceptable
idle when warm.

Thanks,
Chris
