Hi All, I'm new here and want to say thanks for any help.

My 95 G20 Conversion has just had a new AC compressor and return line (front and rear AC). Prior to repair, on acceleration, the AC would barely come out the the vents and lose coolness. When I let off the throttle, AC blows cold and strong.
It still have these symptoms after repair. My best guess is a vacuum leak, bad line or regulator which seems to redirect the air-flow when the vacuum pull is low .

Anyone have any thoughts or similar experience/solution?

Thanks much,
Curt
