The throttle plate may be stuck open, a binding cable or binding throttle shaft or black sticky/ gummy soot that may hinder the throttle plate to close and let the idle air controle valve do his job.
You may need to buy a throttle body cleaner.
Remove it and find out what is going on inside.
Let me know if you need details for removing it.
