Has anyone else noticed that their idle is really lumpy when the A/C compressor is running? And, I don't mean a steady vibration because of the extra load, but irregular mild shuddering vibration. When the compressor cycles off, the idle is lumpy coming back down to 600 RPM and then is more smooth until the compressor kick back in and RPM goes back to a lumpy 750. I've check MAF, MAP, cleaned PCV, the throttle body is squeaky clean , fuel trims OK, no cylinder misses detected by PCM.
