I have a 931 euro spec. from 79, it has some problems when you start it, it can idle at 1400-1500 rpms, when you try to drive it, it nearly dies when boost are building up and the car nearly shots down, when you leave it at idle again there is no problem.
When the car warms up, the problem gets worse and in the end it can't even idle anymore and dies.
I have changed all vacuum elbows and vacuum hoses so vacuum leaks should be eliminated.

So now I suspect it is the WUR which makes problems but what is a common problem with the WUR? I have to replace it? clean it or?

Lau, time for a CIS test to see what's going on with your system and control pressures. Here is a tutorial:

Hopefully, you're able to find a CIS test kit in your vicinity. I used to carry them, but the supplier was so unreliable, I had to drop them.
