seen some cars with with vacuum hoses routed wrong, not per hood diagram sticker shows. and not having hoses on wrong VSV nipples.!
VSV valves connected wrong or valves cracked.
the only vacuum hose that has a device that leaks is the PCV , and the valve there has 1.6L sized orifice controlling that. (it sucks combustion fumes not air)
booster no leaks air ever. (brake)
VSV EGR is closed, it idle.
vsv evap valve is closed until moving. closed at idle.
VSV Dash pot, diaphragm do not leak in fact non do on car. this valve is closed after 15seconds engine just started. can be seen to do so with eyes on it.
FPR does not leak air.
EGR diaghram does not leak air.
3speed tranny modulator must not leak air if car is 3speed, 5speed stick has none.
map sensor must not leak air, end to end, MAP nipple not broken off.
this is my vacuum leak finders post.
