1990 Oldsmobile Royal 88 mileage: 125,000. Unable to maintain engine temperature to 190 degree were I can maintain proper temperature for the heater and for engine. If setting idle it will go up to 210, but when you go on the road for a test the temperature drops to 140 degree's. Can you advise what is wrong? I replaced the thermostat twice with a 192-degree thermostat.

You may be having a coolant circulation problem that is possibly caused by the water pump. We have seen the vanes on the pump corrode away to the point where there is very little coolant circulation.
