I should have mentioned that before I replaced the cooling system, I wasn't having the overheating issue (I was having the other idle-related issues).  I replaced the cooling system because my water pump had a small leak, a cracked fan blade, old radiator, and most of the hoses were original.  I can't seem to win with this car...

You might have a very small pinhole leak in the VOD as someone mentioned. Recently I was in my VOD and there was a small amount of coolant pooled in one or two of the recesses. I cleaned up the area and pressure tested the system and kept noticing a little bit of coolant appearing. At first I thought hoses were leaking but eventually found tiny pinhole leaks in the aluminum block. Later I spoke with someone else about it and he mentioned that owners are seeing more and more tiny pinhole leaks in that area. I think that is due to years of corrosive junk that accumulates in the VOD. If you don't find leaks anywhere else you may want to remove the manifold and get into that area and investigate. While you're there you might as well clean up the area. Some people put a protective sealant in the VOD though there are disagreements as to what works best. If you find a pinhole leak then the additives to the coolant that some are suggesting should work.
