    So, by default when the solenoid gets 12 volts (when the car is running), it extends the thumb screw to contact the throttle linkage to open it to raise the rpms so it wont stall when things like AC are on. when you shut it off, it retracts and closes the throttle to prevent dieseling. Dieseling is when you shut an engine off, and it kind of pops and pings and keeps running for a few seconds.
