I hate this one feature of my P11, 2002, Infinity G20. When the A/C compressor engages, the idle drops like 200 rpms. Is there anything I can do or just suck it up and accept?

This is common on 4cyl, and even some 6cyl cars. The increase in load is enough to cause a temporary drop in rpms.

If it stays down, you may have an issue.
