My air conditioner works fine when truck is at idle speed. When driving at normal speeds and accelerating the compressor will cycle on and off. System has 32-35lbs at idle and fluctuates when rev motor with gauges attached. Any suggestions?

How to tell if your A/C system needs refrigerant: look at the LOW pressure gauge reading when the engine is OFF. On an 80 degree day, the LOW gauge should read about 56 psi or higher if the A/C system contains an adequate charge of refrigerant. On a 90 degree day, the LOW side reading should be about 70 psi or higher. If the LOW gauge reading is less than this, the A/C system probably needs some additional refrigerant.
