Intake Manifold Hoses

[solex3274]

Over the winter months I replaced a number of cracked and brittle hoses under the intake manifold on my 1988 934S. Now that it has all been put back together and the manifold installed, the engine will not hold an idle. The hoses were labeled when removed, so I thought that they all were installed correctly, but you never know.

So either I installed a hose incorrectly or some thing new has developed over the winter months. The vacuum lines are installed correctly.

Step 1. Does anyone know of a good drawing that I can reference to make sure that the hoses under the intake are all going to the right areas?

Put a vac. gauge on to see if you have leaks.
If it runs and wont idle maybe the connections to the idle control valve came off.
just a few hints

Hoses look good, I will move on to other basic areas such as spark. In addition I may have bent a pin on one of the fuel injectors so that will be looked at.
