That's actually quite a normal reaction. Even race cars run better when the weather tunes colder because the air is cooler & denser which equals more HP per unit of fuel burned.

Cold air intakes lessen the problem because they draw air that is moving at a high rate of speed into the motor and is therefore cooler than the "standing air" temp within the engine compartment (which is why a short ram air intake is less effective as the temps rise versus a cold air intake)
