Melted vacuum hose destination

I just got done putting a co-worker's 1995 Contour with the 2.5L back together from replacing the alternator, valve cover gaskets, and upper intake gaskets. In the process of putting the upper intake on, I came across a vacuum hose that has melted and I cannot determine where the other end should go. The one end and the melted end are circled in the picture at http://www.members.aol.com/Rod2414738/Car_Stuff/hose.jpg

She's recently moved here to Iowa from Texas and has mentioned that the car doesn't like to run when it's cold. While I had the upper intake off, I cleaned the carbon sludge from the intake as well as the throttle plate and IAC. I also checked all 6 plugs and wires. It appears they haven't been on the car for a horribly long time and I didn't see a reason to change them. She is right though, the car doesn't like to run when it's cold, and I'm suspecting this melted vacuum line could be the culprit.

Would someone with the Duratec (preferably a 1995) check the vacuum line that goes to the carbon canister in the rear of the car so see if that's where this hose goes? Anyone gonna have their Contour/Mystique up on jackstands this weekend?

I dont have a 1995 and that line doesnt look familiar. I suggest posting over in the troubleshooting over on contour.org.

Well, I took another look at the Contour. I discovered that when she starts the car, the vacuum secondaries don't change. It appears that either the vacuum servo has a hole in the diaphragm or there is no vacuum to it. When I had the intake off, I did operate the linkage to make sure the plates were clean, so I know it's not seized. I didn't however hook a vacuum pump to it and see if it would operate and hold vacuum.

With the car idling I removed the vacuum line from the EGR valve and pulled a vacuum on it. It held vacuum, but had absolutely no effect on the idle of the car. The engine was up to temp though, but I believe the EGR should still be closed at idle, even on a warm engine.

So, I figure I'll be pulling the intake again and chasing vacuum for the secondaries, at which time I'll pull the coil packs and try to find a home for the melted vacuum hose.
