RE: [DML] Vacuum Solenoid Test

[Travis Goodwin <tgoodwin@xxxx>]

I don't own a vacuum gauge, but I do have a finger. When I was running all
the other tests on it, I disconnected the output line and put my index
finger over it. This was a risky procedure since the engine was at operating
temperature. The vacuum was definitely there. As I revved the engine, the
vacuum never changed. It was constant. That was what I figured was causing
the over advance at idle.

I'm thinking there's a broken electrical connecting inside the solenoid
which prevents it from being energized.
