Well here we go again. My Outside door on the hood will not respond to changes in engine vacuum very good. I checked the vacuum with a gage, and it falls off normally while driving, but the dorr never seems to move. It even takes a while to open fully after I shut off the car. All of the mechanisms are free and move fine when you move the door by hand, but just doesnt seem to move at all under normal acceleration. It will start to move if I really hit the gas in 4th gear, but not enough to do anything. What if I took the old check valve I have laying around (Don't worry it is stuck shut so I'm not destroying a good used one), and drilled through the thing so it looked like it was still there but it has no function, would that make the door respond more.

If you are going to do that, just run a direct vacuum hose to it. And while we are on that subject, just run a straight hose to it anyway to make sure your vacuum source is open.
I would try blowing on the gold end with an air hose to see if maybe something disloges. I have had some success doing this from time to time.
