Auto Parts: help, coolant temp, mitsubishi eclipse

Question
it is a 2001 mitsubishi eclipse GT have a problem when i start my car in the morning most of the time
when its cold it idles at about 1 then drops down very quick allmost dies
then goes back up to about 2 rpms then drops back down till it allmost
dies again it does that for about 5-10 mins till warm is the problem
the IAC or something else PLEASE HELP  

Answer
sounds like it might be your coolant temp sensor or perhaps even a vacuum leak. next time you start it lift the hood and listen for a whistling noise. if the iac was bad it would just die out. by the fact that it is changing the idle shows that it is working. do you have any check engine lights on while it is doing this?
