Rough when cold out

My LS last winter and now this fall is running rough when first started then settles down after a few minuets. If it's above 65 degress out in the morning it runs fine...any ideas?

is there any lights on like service engine soon light?

no-offence...but if there were I wouldn't be here asking : ) No lights, just "surging" idle for a few minuets after start then it settles down....warm out in the AM no problem, normal idle. Anything down in the low 60's and less then it idles rough for a few minuets. I've changed PCV and all coils/plugs/gaskets in past year...car did it last winter before fixes and does it this year after...do not feel it's a result of any of those changes since it happened b4 and after.

Try cleaning the MAF, and IACT sensor with CRC electrical cleaner.
