'96 Sport 1.8L AC does not blow adequate cold air

[rasmeidirtrider]

Thank you very much for the information.
My last question, the sticker under the hood said:

SAE J639 Charge R-134a Refrigerant Oil
Max 0.65kg (143lbs) 0.15kg (5.3oz)
Min 0.55kg (121lbs) Model No. SS10V1

Are these the maximum and minimum capacities for charging the refrigerant oil? And Do we need to monitor these exact numbers for proper AC performance?
