something you should notice fif yours is a manual, make sure before you start your car your in nuetral and as soon as it starts to rise what seems to be higher then normal release your clutch and your rpms will drop, i dont know why but mine does this everytime

I'm pretty sure it has something to do with the idle speed. Your car maintains a low idle rpm if it doesn't have a load, and it should raise that a bit more once it starts seeing a load (when you put it in gear).

i know that i was talking about while your still there in nuetral just release the clutch. when you start it and you keep the clutch in it will raise, but the second you let go of the clutch mine always drops. i can do it imediatly or 2 seconds in it always drops the rpms instantly

This is completely normal operation. The car is trying to heat up the catalytic converters as fast as possible to reduce emissions.

If the coolant is too cool, then the engine will be inefficient because it cannot completely burn all of the fuel.

That's just the temperature the coolant has to get before the thermostat opens up. But all of that gas is heating up metal, which, is then heating up the coolant. It's like when you boil water, the stove flame underneath may be several hundred degrees, but the metal pot may only be a couple hundred degrees while the water is only a bit over a hundred.

You don't want to wait until the water is anywhere close to boiling, because, water will produce steam and start pressurizing the cooling system below 212°F. Also, it takes time for the fresh coolant to flow through.

Mine does it too. Most likely because we have heated o2 sensors and it'll help get the motor into closed loop operation to reduce start-up emissions and improve fuel economy.

It's just because the added resistance of the transmission and it's cold, thick fluid.
