Citroën BX weird idle

It's pretty normal after a cold start but whenever the engine heats up even a bit, it gets like this.
It's a 1.6 GTi Finnish specialty - Think Pug 309 1.6 GTi, I think it's the same engine. So it has some Bosch L-Jetronic injection.
As you can see, you can stall the engine by pushing the hose going to the AAV - or additional air valve, whatever you want to call it. :)
