I know this, I am mainly asking what should the value be for the vacuum supply to the 7 port switch. I do not care that my #1 and 2 lines do not hold vacuum. I just want my center vents to work for the time being.

Trying to figure out if the vacuum supply is weak at the 7 port block or if it is ok. Then I will go from there.

I had center vents a few months ago and now I do not. Plus my transmission shifts like crap at low speeds which also could be a low vacuum issue.

Ideally the car blows up and it rains money in my house so I can get a different car. But until then I just need to know the amount of vacuum I should be seeing supplied to that 7 port block.
