Change the IAC Valve.

definatly sounds like IAC valve

Could also be a leaking injector which is causing it to puddle fuel

Start by cleaning the IAC though, cheap and easy fixes first

Did you clean it good? Is the plunger mechanism stuck inside it? Maybe it just needs a replacement. I know its probably tough to get parts over there so maybe try cleaning again with carb cleaner to get any carbon out.

Have you tried a new fuel filter? Clean your MAF, K&N air filters can have too much oil and cause issues in the intake tract.
