Since the idle air control valve is supposed to manage the idle speed of the engine, a bad valve will certainly throw that out of whack. It will cause the idle speed to randomly fluctuate to different speeds rather than stay at one constant speed. The idle speed may be too high at one moment and then too low at other moments.

Why is my Durango fan not working properly?

I had a very similar problem with my Durango, recently. It is very likely that the electric fan is defective or intermittent unless you are losing coolant and/or oil without leaking, then you may want to have your coolant tested for emissions. If it contains emission you may have an internal crack in your block or a damaged head gasket.

What causes excessive pressure in the coolant system?

With a cracked or loose return line, air will be sucked back into the rad as the engine cools. Same thing happens if the rad cap leaks air as it cools. The head work is ok. Repeated tests show no gases in coolant system. System was pressure checked for 3 hours with res line plugged at the reservoir.

What happens when your coolant system is full?

You may have air in the system. When the engine is cold make sure the rad is topped off and the res level is at least mid-way between low and full. When the engine cools, if the system is full when hot, the res level will decrease and usually increase when hot. All this is assuming the head work stopped that problem.

What causes the coolant to return to the reservoir?

Repeat test of combustion gases in coolant system came back negative. I think your response of the reservoir line having a crack or something that allows the coolant to return to the radiator is a good option to pursue. Coolant flows to the reservoir hot, but does not reverse flow. Same level cold as when hot.
