    This line has a check valve for hvac system

    You are on engine side?

    I ran a new line on that

    My vents have been acting up.

    Original line I can’t even blow through

    What type of gauge are you using

    Basic with numbers or actually a vacuum gauge that says
    Clogged exhaust
    Late ignition timing
    Intake manifold leak
    Below the numbers in red box

    well after finally getting my laptop and data logging, the rough idle was maf that seemed to have lost its brain. new maf idles like a champ, low vacuum was the maf actually not fully seated in the housing. musta got hit by something. relieved it was an easy fix! thanks for all the suggestions!!
