Doesn't sound good. My Mec. didn't measure the highside pressure and I couldn't get a good look at the sight glass. So I can't report on that.
What I can say is that it worked better before he charged it. In fact I think my problem was do to the fact that the car was over heating and the compressor was shutting off while sitting in traffic.
Is there such a thing as over charging?
I searched the archives for this topic, but I found many references to "Steve's" disertation on the Black Death, but I didn't find it. Are you the Black Death Steve?
