No. Something looks wrong.
It should be opening right away and not sticking.

Check all the vacuum connections first and make sure no leaks.
With the engine off. Apply a vacuum (suck on it) and see if the diaphram inside the actuator is defective.

Correct. Down is bypassed closed. Up at idle in park is normal for full bypass.
