Clean out your IAC, check TPS, clean MAF, and clean the TB, reset the computer. If that doesn't work, report back.

disconnect the batt, turn on the headlights, leave it over night. next day turn it on and let it run for about 2hours at idle, DONT touch the gass

Is it a rough idle?
If not I wouldnt worry about it too much.
I had to set my idle at 1000 just to get it to stay running.
