hey guys..my wife's expy's air conditioning wasnt work, so i bought an 11 oz can of refig. i put it in and on my gauge the pressure fluctuates. when the compressor kicks in, the pressure is fine, but when the cluch releases and the compressor kicks off, the pressure is low. i have never had this with any other vehicle, usually the pressure stays constant throughout the compressor trigger on/off. i want to make sure it works for her...i didnt want to add too much, but i want to make sure i have enough in. any help would be appreciated...thanks
