Idle issue.

Idle issue.
I need help please, I have a 2004 mustang GT. I recently replaced the idle air control due to my car constantly dying. That sorta fixed the issue, now when I when I come to a stop and slow down it idles around 2 grand before dropping down to around 300 rpm's and finally it shoots back up to around 800 rpm's. Sometimes the car does completely die but will restart right back up. I've replaced all hoses, PCV valve and Idle Air Control. Car has been hooked up to diagnostic machines and it doesn't read anything is wrong with the card. Any ideas?
