Vacuum at idle
Just curiouse if anyone knows how many inches Hg I should be pulling at idle, I was wanting to run a basic vacuum test as part of a maintnence inpsection but I'm not sure what kind of vacuum these things even SHOULD pull.

Good question..
I installed a vaccuum gauge under the hood so I could keep an eye out for leaks. How much vaccuum should these cars be pulling??

I asked a similar question recently after installing an aftermarket vac/boost gauge. It seems the general consensus was 14-16 cold, 18-20 warm at idle.
