Audi Rhatt

Hello I have purchased an86 CS 5000 Turbo Wagon, and as I was working out the bugs (someone used it for hauling hay REALLY) I have come acrossed the following things I am wondering about...

1. It has a hesitation (like it is missing )when I push on the accellerator.
2. THe Heater Motor does not work (It has the climate control system)
3. The fuel pump is loud...( I have worked on Bosche fuel injection for a few years and it seems like it is louder than others I have worked on)
4. I have a few vaccume lines off (does any one have a diagram???
5. It has a small exhaust leak when you first start it up of course it stops when it get hot.)

Any help would be greatly appreciated..
