How does the condenser look. Does it have a lot of bugs or bent over fins? Second thing to check is if the fan clutch is working correctly. You may not be drawing enough air through the condenser. The mist the condenser with water may help indicate an air flow issue.

Could have a partial charge or bad reed valves. I would recover the refrigerant, recharge after checking the O tube, and then get the pressures..Hope this helps..
