[s-cars] ISV hose collapse on idle.

[Andrew Lee Jackson]

Salut S-folks.

Title says it all.

I traced an audible vacuum leak back to the the ISV to IM hose. Closer
inspection revealed that this hose was collapsing onto itself and was
sucking air past the clamps at idle. When I revved it, the hose would
balloon back to it's "normal" state.

Tightening the hose clamps resolved the vacuum leak (at least audibly),
but the hose is now collapsing to a point where it's almost completely
flat.

A search of the archives showed me that I am not the only one who has
experienced this phenomenon. No info regarding a definite "fix" tho.

Is this even a "problem"?



Any insight would be greatly appreciated.
