HELP!!! Odd Idle

When my car starts it has a normal engine speed at about 2500 rpm and when it drops down to about 1800 to idle it jumps up around 22 or 2300 rpm. This happens every couple secounds. It seems that its trying to stay running with short bursts of fuel. Any ideas on a problem? Thanks for the help.
