Default Rough Idle at Startup

Yesterday morning I fired her up and she ran really rough almost like it was going to stall. After about 10 seconds I powered down and restarted and it ran smoothly. I will list the conditions below. Please post if you have had something similar and if you ever found it to be a mechanical issue or just a fluke. I believe this has happened a total of 2 times in 2 years.

Time - 6:45 am
Temp - approx 30-35 deg F
Fuel - Gas light was on (I'm thinking this may have had something to do with it...but not sure)

Thanks for any info anyone is able to provide

I've never had it happen personally but I beleive I read something a few weeks/months back about a similar issue. Have you read through the IS250 carbon build up thread?
