Low Idle

I dont know if this is normal or not but when I start my car no matter what the temp outside is it just starts and revs at 1000, it doesnt idle up at all. It runs fine and all it just seems abnormal to me.

my ka is being bitchy and idles all over the place, first it jumps from 1000 to 2000 a couple of times, then idles at 1500, then oscilates down to 1000m all this during the warm up cycle, otherwise on normal idle it twitches and shit and pisses me off =\
