As mcduck pointed out, it may be your coolant temperature sensor. To help confirm this, the next cold day that gives you the same symptoms, turn off the ignition, disconnect the AMM, the try starting again. If this helps, it indicates that you have a lean fuel condition. On mine, disconnecting helped, so I shut down the engine immediately (while the engine was still cold), re-connected the AMM, and on restart, it ran rough again.

In addition to the suggested coolant temperature sensor cause for a lean fuel condition, vacuum leaks can also be the problem.


The "disconnecting the AMM" trick is known as "limp-home" mode, which forces a static "slightly richer" fuel mixture in the event of an AMM failure. The car won't drive very well like this, but it's a great and simple little cold start test.
