Possible causes for the problem are :

1. Faulty thermostat.
2. Clogged heater core.
3. Heater valve ( if equipped)
4. Lack of coolant.

You need to check all the above. Flushing the radiator and heater core would be recommended as you mentioned the coolant being dirty.

If the ISC system used is equipped with coolant hoses, lack of coolant would cause that. The other would be a faulty Idle Solenoid Control motor.

If the idling speed is adjusted out of specs, it would surge. Check for vacuum leakages.
