Vacuum leaks on 4kq

[R Mangas]

    The hose that runs from the intake manifold to the idle valve often
splits, and I've heard that the ribbed rubber plenum from the fuel-metering
head to the throttle body can get cracks in the underside.  There's a big T
pressed into the underside of that plenum too- if the T pops out you'd have
a big leak.  Finally, it's not that hard to be wrong when you think you've
got that plenum correctly seated back onto the airflow meter.
