so what rpms are for what pressure?

i think pressure will vary with rpms?

any simple table from 3-4 readings it should have?

and yes ofcourse i started from vacuum lines

i ve changed almost all hoses i could find

but still no luck

what hose r u talking about Rob? cause there are 5-7 of them
and they give different result

(like big one off throttle body on the top: when removed car just dont iddle at all!)

also i hear some whistling noise from around the power steering pump/reservoir, checked hoses there but they seem to be ok

removed manifold and changed couple of hoses under it, but on the vacuum diagram, there are 2 more...

geez how its hard to change them! (gonna take alternator next time to get access. as removing manifold and putting back manifold is 2 hour job... )
