Whats my normal vacuum, and where to test?
I suspect a vacuum leak, but I don't know which lines to test and what the numbers should be for each line.
I'm used to diesels that don't have so many lines.
Thanks

I get 22" at idle on the port that feeds the fuel pressure regular on the left rear of the upper plenum.

So should it be the same number for every vacuum line and system, OTHER than the PCV-intake line?? I think I remember hearing that the PCV is a controlled vacuum, so the value might be lower.
But for every other line should I see the same value as I get when plugging directly into the intake?
