Yes, we vacuumed it for approx 30 min befor charging. We added about 3 ounces of PAG oil.

i work on refrigeration units all day, i would like to know what your head pressure is, high side or red on your gauges. the charge you weighed in from what the sticker said was the weight for r-12 or for 134a, i know you put 134a in the system from what i read, but the system will use less freon with 134a than an r-12, your probably over charged, also you condensor coils are probably dirty and plugged with bugs, clean it out really good and see if that doesnt help your problem.
