The spark plug gap can cause the RPMs to fluctuate, while idling. The more probable cause of the fluctuating RPMs is a bad camshaft.

It depends on how long you are idling, or how fast you are going. If you know you are going to be idling for a long time, it's best just to put your car in park.

Have your sensors checked.

If it blows warm while idling and cool as you accelerate down the road, the coolant is low and or doesn't have proper mixture for your avg. temperature.

Check and see if the fan cluch is good. Your fan. At higher speeds, the fan is not needed due to the high airflow. At low speeds and idle, you need the fan to operate to cool the car.

Not sure what you mean by "idle funny". If you mean the engine revs up and down while it is idling, the problem is most likely a dirty/clogged air filter.

Yes it is - only when idling and if I turn the heater on it cools down - thermostat?

Engine temperature rising when the engine is idling is normal. The car is sitting still and no air is entering the engine compartment. This will cause the engine temperature to rise. The cooling fans then come on and the engine returns to a normal temperature. Unless the cooling fans do not bring the temperature down, you have no problems and this is totally normal.
