troy-cryer makes a lot of sense also,maybe try letting some gas out of it and see what happens,because if it's putting out 38 degrees at the vents there can't be a hole lot wrong as most oem stuff I work on will only put out about 45-55 degrees at the vents.....

Not a auto ac tech, but the metering device sounds like the problem. High head usually gives you high back pressure. A restriction will drop your low side pressure and the more refrigerant you add the lower it will go, hence slugging the compressor with liquid, not good. Is the suctions line sweating?
Is the metering device rated for 134A? 36 to 38 degrees to cold, kinda also sounds like improper size condensor. Wish I could help more, just thought I add my 2 cents. Stu Cool.
