I'd like to isolate the VCV and the modulator from the vacuum system. Therefore, please plug the supply line as directed above and drive the vehicle. If the vacuum problem is eliminated and you maintain brakes, then the VCV might be considered the culprit. If the brakes are lost and the engine still won't shutdown, then you've got more problems than the modulator and the VCV.

Here's the valve.........a bit costly, however.
