Expansion valve may be having issues. Also if there is an inline filter it may be partially clogged.
possabally a restriction,,, your pressures should be in 70 to 80 degree weather,, 35 to 40 on low side and 175 to 190 on high side with ac running,, if low side is less then 35 and high side is 175 to over 200,, you have a restriction
