revs erratic first thing in the morning

My car has an annoying problem that when i start it first thing in the morning the revs drop and rise erratically then as soon as i pull away and and drive to the end of the road and stop then it ticks over perfectly it dont bother me that much but i was wondering if its the start of an underlying problem?

Cheers Rich.
