Need troubleshooting info on Turbo Control Solenoid
I've searched the forum and looked through the FSM for info on testing/inspecting the turbo control solenoid (the one mounted on the ACV) but I can't find any info on that design solenoid. Does anyone know the flow characteristics of this solenoid energized (12v applied) and de-enegized? I know a few people have tested them, so if you guys still have your data, please post it. TIA.

Lacking a picture: the black nipple furthest from the electrical connector is the "in". The other black nipple beside it is the "out". Under the plastic cap on the other side of the connector is the "vent" nipple.
When the solenoid is energized, the path flows from "in" to "out".
When the solenoids is not energized, the path flows from the "out" to the "vent".
I test by putting a chamber on the "out" nipple. I apply 25" vacuum to the "in", energize the solenoid. It should snap open. I then pump down the vacuum chamber to 25". I release the voltage and the solenoid should snap closed, dumping the vacuum thru the vent.
If it sticks or leaks at any point in this test I scrap it.
