Default High RPMs on startup

I hope someone can please help me out when I start my vehicle my RPMs go way up to around 3,000 to 3,500 but when I put it in gear as quickly as I can before my RPMs go up that high they go back to around normal I have a rough idle though and vehicle will stall seems to only happen when my vehicle is cold. Any advice would be much appreciated thanks in advance.
