I just finished replacing the compressor o-rings with HNBR and doing an evac and recharge on my '93 Sport. It was my first time using a manifold gauge set and dong more than a top off, so I am a little green. I couldn't find any system capacity spec for the 1st gens, just one for a '94 which was 22oz of 134a.
1.) Does my '93 have the same capacity as a '94?
I got between 1 1/3 to 1 3/4 cans(so 16-21) of 134a in the system with pressures swinging around ~30-50 low and ~140-180 high with the compressor cycling about every minute while idling in the driveway. Vent temps stayed right around 39-41°F with ambient around ~67-70.
2.) The low side pressure and vent temps seem on-target, but the high side pressure seems about 50psi low from the reports I have seen. Do I need to add more refrigerant?
