Mist the condenser and post pressures & temp.

I did. Pressure dropped little bit but not air temp

Seems to be cycling pretty quickly. 1.5 Lbs is the correct refrigerant; what's the sticker on the radiator support say.

[mcFish]

Yes, correct

I've got to get back to some corporate stuff. Check that the heater core is not allowing hot water into the core when in a/c mode. As in the other post. Have you overloaded the oil capacity?

I didn't evacuate/refill oil. And I assume yellow dye is OEM Nissan Luminous oil.
Hot coolant is always flowing through heater core here and only air flow regulates by diverters.
I've checked heat - works well, heats up and shuts down right after I've put temperature knob to Low.
The suction line is pretty freezing, just not enough time to pump it through evaporator.
