After acceleration, 30 seconds or so, the vents get cooler and the 3-5 value return to the lower 40s F.

I do have a faulty duo-valve, but that's relatively under control and not a part of this issue. I believe there is enough R134 in the system and other than when I accelerate the ac works great.

I believe there may be a vacuum control/issue that could shut the compressor off in his instance but not sure if that's the cause. Any ideas?

Here are some ACC values

1. 85. , 78
2 94. , 82
3 62. , 40
4 64. , 40
5 57, 39
6 173 177
7 17. , 15
8 138, 137
