From what I've read elsewhere, the cheapest thing to be wrong would be a leak in an air hose (after the air flow has been metered). If you can't find it by manipulating the hoses, apparently spraying carb cleaner in the vicinity will change the idle when it's sprayed near the leak - it could be a gasket/O-ring rather than a hose.
I had an Astra with the same problem, and it did have a split hose, but I'm not familiar with the arrangement of hoses in your car.

Sticking idle control valve?
In an injection engine?
Yes.
