my emails subscriptions keep failing
so I did a long post and will check tomorrow,for any progress by you.
best i can tell , huge vacuum leak. there.
its easy to prove,.
the tactic is simple starve it of all normal air paths see what it does.

a video works

this guy does it right.
the other trick is knowing what will leak and not. ask !
one guy here bought a cigar, and blew smoke in the vacuum booster hose. ( he did not breath the smoke,)


i will now show my page for normal
any like from the TV plate to the intake valve are prime suspects
all gaskets all seals , all hoses, any cracks there, for any reasons in that path are suspects. vsv ,FPR, or any thing with a vacuum nipple and even breakbooster


this wrong engine, but imagine maf to the left more and bingo behind the air cleaner
PCV hose leaking is vacuum.
(there are only 3 normal paths of air, TV is not one, at idle) all others are bad. (and can add up, just like taxes bad)
