I am sure there are more things:
Sure, many things could be a problem, but if the car starts just fine, has the power, runs smoothly, and only has idle issues, especially at AC load, then what could that narrow down to?

Again, if I let the RPM drop quickly, then it has tendency to stall. If I do it gently (engine braking down to close to idle) it will dive, but recovers and stays OK.
