After doing a new liquid line and orifice valve my a/c still didn’t work right. The high pressure side would spike and suck down the low pressure to 20 psi where the low switch would shut the compressor off. Once the low side rises back to 50 psi the compressor kicks back on and the cycle starts all over again. So after posting here the general consensus was the accumulator was clogged. Well I installed a new accumulator and flushed the evap out. After placing the system under vacuum on the pump for an hour and then letting it sit for another hour I charged the system. The problem still remains. Cycling on and off. Now what?
