My AC works fine at idle. Once the rpms reach about 3000 when accelerating the ac stops cooling. I hooked a pressure gauge to the cars ac system and the pressure is normal at idle. Once you accelerate the pressure drops very low. After the car idles for a minute or so the pressure returns to normal. Also the cooling fans start running at high speed when the ac is turned on (that's new).
