Cold start stalling in '94 9KCSET

My '94 9K CSE 2.3T (98K miles) has been stalling when I start it in the morning. I usually fire it up in the morning about 10 minutes before heading to work--nice to have a little heat in the morning.
It idles solidly when warm (I'm assuming no vac leaks--it has all new silicon hoses), and only seems to stall when it's cold. This morning I started it up, and it idled fine. When I came out 10 min later, it was stalled out. It's been doing this for a number of months, but usually only sputters and then the idle regains its speed--it has gotten worse. My old 900's would do this due to a bad AMM, AIC valve, or cold start valve, but I'm not sure what would cause this with a trionic car.
I've 'de-gunked' the AIC valve a couple of times within the last year, changed the plugs recently and gapped 'em correctly, DI cassette is new as of a year ago, and I run fuel injector cleaner through the system every 3500 miles or so.
Any thoughts or suggestions on what to check? Air intake temp sensor, perhaps?
