Rough when cold; smooth when warm...???

I'm wondering if our cars are temperamental about air temperature. Is there such thing as having too cold of an air charge? For the majority of the winter, I've been racking my brain trying to figure our if I have a bad IAC, vacuum leak or something like that to make the car idle rough (after warmup). Today, I took the car out and noticed that it was not idling rough. The temp was close to 70* today, BTW. Am I missing something? Are my plugs too cold for the cold weather (NGK T6IX)? HELP!!!!!!!!!!!!:(
 


mine does the same thing. i dont think itd be your plugs though. i keep thinking about doing a tune-up..

i cant wait until the weather is nicer though. it was about 40*+ today and i was able to go 0-100 with only 1* of knock at the shift from 2-3.
