Puff the Magic 9-3

An occasional-to-frequent puff of smoke when starting up a Saab 9-3, and the engine seems to threaten to stall out...

When I start up my 2001 Saab 9-3, the ignition turns over and the engine starts, but the engine sounds like it might cut out. This "fake stall" might happen once or twice.
When this "fake stall" happens, the engine RPM drops, then goes back up to the normal idling RPM. At the same time as the RPM drop, a puff of thin white smoke comes out of the exhaust.
Once the car starts up, it runs fine. I drove it 400 miles last weekend, and apart from the puff and the start-up oddities, it seems happy once it is on the road. I've read of turbochargers causing smoke, but the turbo functionality seems okay, as well.
I use my car infrequently, perhaps once a week, and the mileage is 53K, but I have been changing the oil every 5k miles.
I had to have a new Direct Injection Cassette installed at 45K. When that part failed, I stalled out in the middle of a busy intersection, so I'd like to know what might be causing this latest problem before taking it to a repair shop and spending thousands of dollars.
