Hmmm, brilliant details you've given here.. but unfortunately I don't know that engine well enough to even guess on this one, so I'll leave it to someone else who might know.
Good luck fixing the probs mate.

Might be the idle air control valve, which is located under the intake manifold near the firewall. I'm having the same problem with mine. I've read that they can be cleaned, but I have yet to find a way to get it out, short of removing the entire manifold/throttle body assembly.
