@Brian- I got a constant pressure half way between 5" and 10" no matter what throttle point and that number did not change during shifting. Is that what is suppose to happen?

Ideally, you'd like about 10-12" vacuum at idle. This typically remains steady unless you get more than 1/2 way into the pedal...........then it will start to drop..........at about 3/4 pedal it will be down to 5"...........and at full pedal it should drop to less than 2".
If there is no change of reading no matter what the pedal position, further tests are necessary to determine the culprit. The tests will be identical to the previous tests where vacuum is measured at various points along the system.
