Kevin I believe you meant 340 grams, not mg ;) Add two more cans of that size and your A/C will be fine. Your system is way low on refrigerant at this moment. Taking readings when the system is only 1/3 charged makes no sense at all. Charge it with 1kg of refrigerant and then check the pressures. Good luck Tom Niemczewski vin 6149 (in Poland!)
