Question Idles rough on cold start

My car just started Idling really rough when I start it...Once it warms up it runs great????Once I drive like one block it Idles fine....Could it be a O2 senser not warming up??.. Or could the maf be dirty??

what year car do you have? stock injectors?
i have a stumble after start up; i was told it is because i put bigger 1998 injectors into my 1999 firebird and LS1edit is unable to adjust for initial startup.
