Take the vac hose going to the canister off when the vavle is pulsing and put you finger on the port of the valve..does it have pulsing suction??
If yes, then unplug the connector..does the valve shut OFF ?
If NO to either , it is full of crap and needs to be cleaned.
That is why my early post said to check flow.
I am not concerned with it being clear..I am concerned if it CLOSES...cuz if it DOES NOT , then it will fit your condition...get it ?????????????????????
Dirt can hold it open and you then have an interior VAV LEAK.....and a vac leak will cause your condition...

Arthur, I really appreciate your help. Have a little patience, I do not know these cars like the back of my hand like you do.
Ok, let me make sure I'm understanding what you are suggesting.
1. When the valve DOES start it's pulsing open and closed, take the vac hose off (the one on the "from" end of the directional arrow -- toward the front of the car, the smaller of the two valve inlets). See if I actually have a pulsing (on/off) vacuum going INTO the valve. I should have the pulsing vacuum.
2. If it does pulse, then take power away which SHOULD make the vacuum stop, correct (since no power = closed valve)? If it does stop, then the valve is working correctly. If it doesn't then something is keeping the valve somewhat open even though the electronics are saying that it should be closed.
Am I understanding your directions? In #1 -- am I looking at the correct side of the valve to check the vacuum? In #2, am I understanding your conclusion?
Thanks.
