Problem Description and Possible Solution
Debris can get into the idle air control valve. This will restrict the air flow into the engine, causing idle speed and/or stalling when cold. The valve can be cleaned or replaced to correct this concern.

Engine dies on start-up about once a week; the engine won't hold an idle speed when cold and immediately after cranking the idle falls to zero and engine dies. Will continue to happen until car is warmed up. Only solution is to keep foot on the accelerator to maintain idle until engine warms. I drive it in Low or with the O/D off to warm the engine faster to keep it from stalling at stops until it warms. Then it will be fine for 5-7 days until it happens again. No correlation with temp or humidity I can identify, other than it only happens when the engine is cold, but is sporadic.
