Re: 99 Caravan AC not cooling

I did vacuum out the system for over an hour. Our outside air temp is 88 degrees with moderate humidity. After 15 mins of idle the low side pressure is 40 psi and the high side pressure is 200 psi. After 15 minutes of high idle (1500rpm) the low side drops to 34 psi and the high side increases to 235 psi. The manufacturers sticker under the hood shows this dual unit should have 2.88 lbs of freon. I calculated this to be about 46.08 oz so I put in 44 oz of freon and 12 oz of compressor oil. I replaced the compressor and dryer with new ones and do not have any leaks that I can find. The compressor is not cycling on/off at all and the air from the ac is now staying around 66 degrees. I'm stumped! Any suggestions would be appreciated!
