I have a loose vacuum hose coming off my intake manifold. It is to the left of 3 others that are in line with each other horizontally. It comes out toward the injectors about 6 inches, turns towards the firewall about 4 inches, then turns down about an inch. It has a broken off plastic nipple in the end.

Any ideas?

I'm going to get hose material to replace some bad looking ones, as I'm having an acceleration problem since my last repair. So I wanted to find out about the one not connected.
