Checked/replaced the fan clutch? That is the culprit of idle overheats in a lot of cases. They're cheap and simple to replace. I'd recommend it highly if you suspect that to be the problem. ALso a bad water pump can do the same thing, if the impeller is slipping ont he shaft. That's RARE but not unheard of especially with some cheap parts.
The engine fan should make a real roar the first few blocks of driving on a cold morning (on cold start). Then it goes away. If you never hear it, suspect it.
Also, I take it that it is truly overheating, not just showing it on the gauge, which is known to be defective. Verify that before you write it off to a bad gauge though!
