holy hell 6K rpm i would not be starting my car again till i find out what this problem is,your going to burn up your bearings and oil pump...first thing i would try like above Unplug your idle controll then start up the car and see what happens,does sound like it pull in to much air plus make sure your throttle body is clean and closeing correct..

this is the part you should unplug
