Hi,

I've noticed that when the temperature drops below 2c my car seems to have a lack of power untill it reaches the correct coolent temperature. The power drop isn't massive but it is noticeable. The question is, is this a sensor on its way out or is it software to help protect the engine/gearbox untill the car reaches temperature? Any ideas?
