Above a certain RPM they open.
There are 2 of them. One for the front bank of cylinders, and one for the rear bank of cylinders.
With the car OFF, you can try to move each one....and see if it moves.
The actuators can go bad. On my '96, the actuators get their vaccum source through red lines that connect to the top of each actuator.
Here is a link to some pictures of my '96....that may help you to locate the actuators...as well as a few other things. You can click on "view full size" to blow the pictures up to see more detail.

Once again this forum and it's wonderful members, like you, have helped me immensely! Knowing where to look and what to look for was invaluable. Found a missing clip that holds the arm into the lever that controls the valve. Should be fine now. THANKS!!!! Tom C.
