Guys I noticed this hose in my car implodes when the car is turned on. I plan to replace casue the hose feels spongy only in certain section. Can anyone tell me what the main function of this hose is and what will it do if I drive with it that way. Thanks for the help

looks like vac hose. just buy some autozone hose its like 75cents a foot.

 

that's a vac hose that goes to the p/s pump idle up valve, which increases idle speed when there's pressure applied to the fluid side of the idle up valve.
When you chance the hose, check for fluid in it, which means a leaking valve.

 

hey SC4Coupe.
can u take a picture of where that hose connects to?
i want to reconnect mine bcs some shop sealed it shut.
