Low side is to high and high is to low.
Expansion tube or weak compresser.
What are the low and high readings at 2500 rpm.
If not much better pull the orfice tube and check for a lot of trash if a lot of trash usually it is compresser trash.
If clean replace it and evccate system and check oil and recharge to proper amount of charge and see what it does.
If a reto fit to r-134 hold the r-134 charge down 10-15 percent.
Let us know how it goes.
