What was the reason for timing belt change?
Timing belt change shouldn't affect the idle speed.
To properly set the idle on a 2.2. There is a non-connected wire(mine is on passenger side under the hood. You ground that out to set the base idle. It bypasses the ICV. Did you by chance have the defrost/ac on? That will increase the base idle to around what you are seeing. The computer on the 2.2s is pretty primitive. It doesn't learn, it doesn't cash. It just uses baselines established by volvo. BTW, turbos really, really, really hate any type of airleak. Did I say REALLY? An unlit propane torch is a good method to search for airleaks. When was your last tuneup? Plugs, wires, cap, rotor, airfilter etc...
