Recently i was changing my fuel injectors and after puting the top of the engine on i noticed that there is a small hose sticking out and i have no idea where it goes. It's made out of two hoses - yellow and black(i think). when car is idle there is a vacum effect, but when you add some throttle - the hissing sound disappears. My contour was choking at idle, but then i basicly took a rubber cap at putted it on the tip of the hose - car runs good now.
Does anyone have any idea where that hose should go?
