Many things could contribute to this, but one of simplest driveway checks would be to remove a plug wire and see if you can isolate the miss. It may be as simple as a plug fouled from the cold-start enrichment. My SL does this every now and then but clears up right away after it warms up and the plug cleans up.

Have you replaced the plugs recently? Check the plugs and check out your ignition wires too. A bad wire with high resistance may be fine after warm up when the engine runs easiest, but during cold starts that extra resistance can cause a misfire. Also, for whatever reason, a lot of folks have found the NGK plugs to perform better than the Bosch. I suspect they may have a wider temperature operating range.
