Engine Revving

Hi, At starting my '06 Limited this week, the engine has been revving to about 2500rpm then drops back to about 1500rpm, then back up to ~2500 then drops back before finally steadying back to its normal idle. This has only happened in the morning. What could some possible issues that may be causing this?

Thanks for the responses!
