H-townbenzoboy,
DO NOT go out and buy any kind of replacement VCV just yet.
Since I started this THREAD I usually monitor it and try to help when I can but I just returned from a 3-week vacation to Italy.
(1) Q - Would you please clarify which MBz YR/Model you have with this problem. I want to make sure you are working from the correct vacuum diagram and that your various vacuum hoses/lines are hooked up properly.
(2) Yes it is entirely likely that your VCV will NOT hold a vacuum and yet be perfectly OK. I say this because it's function is to act as a variable bleed of vacuum from the tranny vacuum control system... thus simulating and signaling to the tranny via the modulator what your throttle demand is. So don't chuck this expensive piece of plastic just yet.
