Welcome back. Your description sounds like a failing compressor or a blockage that isn't allowing the 134A to flow properly. For testing you will need an AC gauge set. Put the gauge set on it and then watch the pressures as it idles and what it does as the engine rpm's increase. Once you know the actual pressures you can go farther but you need those first.
