Re: VRO Vacuum Switch ?
there is no vacum switch mounted on the VRO and nothing that monitors pressure period.
ok, yea it does but typically we monitor it in inchs of mercury or Hg.
its sometimes a difference between old school and new school.
the vacum switch is mounted on the fuel intake side, its looking for a 6"Hg difference.
on intake manifold stuff we measure manifold absolute pressure or MAP.
its the inverse of manifold vacum.
then we can do it in KPa,milibars,inchs Hg or PSI.
gets rather confusing depending on who made it and whose software your using.
but to answer your question, I really doubt your idle issue is the vacum switch and if ya think it is simply pinch off the sense hose while its idling.
