That was a common complaint a few years back, due to the fact that the heater core is a little too much higher than the engine, which requires that extra push it gets when engine RPM's increase. One thing I did do on my Caravan was remove my hoses to the heater core, and use a small external pump with hoses to circulate C.L.R. through my core for a while, then let it sit with CLR in the core overnight.Next day I circulated it through again, both ways by reversing hoses, and then re-attached hoses, bled air out of system, and notice quite an improvement in heat at idle. Once cleaned out, the heater core allowed coolant flow through it better at idle. If your stumped by explanation, take it to an automotive shop, or a Rad shop, and get a quote on flushing that core out for you. I recommend the CLR, but it might be too time consuming for you , but a flush will probably show some noticeable improvement.

Check for an OBII code. have it scanned for free at an autoparts store. it is not the thermostat since you have already replaced it 3 times.Check for the temperature control sensor during scanning..

The head gasket is probably bad. unplug the coil pack and remove the spark plugs and turn key to start, if its leaking coolant will shoot out of spark plug holes, seen it a lot.
