A few observations. You can't charge by pressures, only by weight. Pressures will help diagnose a system, but they won't tell you the exact amount of the charge. And currently, none of us knows just how much refrigerant is in your vehicle's system. So what you should do is have a professional mobil...

How did you charge it, by precisely weighing-in the R-134a or by the pressure readings? It sounds to me like it might be low on refrigerant. A mechanic, who's lift I was using, put the refrigerant back in. He didn't put the full amount in as he said the pressures were good and didn't want to overch...
