Previously the car's idle would "pulse" up and down, I cleaned the
ISV with carb cleaner and it idled better but not "right".

Apparently I have a defective ISV, wondering how it works.
With the ISV's wires plugged in the car won't idle and dies when
the throttle isn't pressed. Unplug the ISV's wire and the car idles but
I get a check engine light.

Nothing else was unplugged on the engine, I know some people have
plugged a different cable in to the ISV and the car ran bad, this
isn't the case.

Is the ISV servicable or does it need to be replaced?
