Looking for suggestions as to what the problem could be.

Vehicle: 94 Chevy Suburban k1500 350 V8

When she is warm, in gear and the A/C is on, it seems to be running rough, not sure if it is actually rough or something with belt. Have watched the serpentine belt and it looks like it jumps every now and then. If I turn off A/C problem goes away, if I take it out of gear, problem goes away. I have check the resistance on the air idle and it within spec.

Any thoughts?

take the compressor off and install 2-55 air

oh shit, it's a suburban so you can get 4-55 air

Well, considering I don't ever get to 55, it would be more like 4-30 air, not all that great. Besides, us old folks like cold air...

maybe the compressor's just tight or something. the remanned compressor i put on my old 4.3L was super tight.

Is there something that can be done to "loosen" the compressor? I know, have a little compressor.

idk man i'm just spewing shit here

all i know is that reman compressor i put on the 4.3 would bog that bitch down something terrible
