Is there a special off topic section I should be posting to that I haven’t found.
EDIT. i removed my rant. we all have bad days.

but since i have completely ruined this thread, i might as well do some testing to get use to how this forum works.

now let’s look at the real thing

testing the solenoid…
looking at the assembly like this
The upper two connections are for the vacuum sensor
and the lower two are to drive the solenoid.

first I removed the short hose from the solenoid to the vacuum sensor
then pried the vacuum sensor and the connection block out of the bracket.
if you remove the solenoid from the bracket, be careful not to break off the fitting pointing sideways

removed two screws that hold the connection block and vacuum sensor together.
Now you can see what is left of a 20 year old foam filter.

I used a $3.00 meter from harbor freight for the testing, so any meter can do this…
Check the vacuum sensor without vacuum.
It should be an open circuit, or infinite resistance.

on the 3 sensors that I tested, they all showed continuity around 5” of mercury vacuum

then I tested for continuity in the windings of the solenoid.
** the readings were all over the place. From very high resistance to almost no resistance. This would back up pauls statement,
