Idle running

Hi
I have Saab 9000 2.3i -93 with Direct Injection. Now the idle speed isn`t very good. When engine is cold there`s no problem but after few miles driving idle running will shake the motor but no very much.
In the vehicle inspection here in Finland all numbers in the exhaust test was ok, but HC is 290 and the limit is 100.
I went to local Saab-service and they check my car with their `computer` and it told there`s a air-leak. So, the service-guy spray some fluid into the intake manifold and the motor running immediately get better. I think the leak-point is in some of rubberseals near the engine beginning the intake manifold.
I change these rubbers, but that doesn`t make the idle running any better. I try to spray some fluid into the new rubbers and that doesn`t matter into running yet. But idle running is still bad. Sometimes it roams a little.
So can you tell is there`s something to do. Every underpressure hoses is checked and I can`t find anything wrong about those.
Can DI-casette make this or camshaft position sensor?
Thank you and I hope you understand my bad english language :)
