Post 1999 Grand Cherokee Rough Idle

When I first start my Jeep, the engine revs up and down erratically, If, before I start the engine, I turn the key on and hold the accelerator down and up three times and then start the engine it idles smoothly. What would be the cause of this?

Thanks for any help!
