Still chasing down vacuum problems. Today what I did was cap of all ports on the vacuum tree except the one for the intake, also capped of 1 of the lines on the back of the upper intake, hooked the gauge up to the other then ran the car. I am still getting the same vacuum reading.
By doing this I eliminated all vacuum lines as a cause of my low vacuum correct??
