20 at idle is about as perfect as you can get steady idle. That shows perfect engine performance at idle. Can you post up the reving up and the let go numbers or post a vid with that information. Those #'s will help determine where your engine is when running up the RPM's and then the quick drop in r's.

If your compressor is making your engine lug so bad, then I'd say you have a bad compressor head. You probably need a replacement and recharge. You could have a bad clutch on the front, causing the drag, but would bet on the compressor as a whole. If this is the only time this happens, you've found your problem and now it's time to either fix it or don't use the AC. Some choices are harder to do than others. lol
