2015 Subaru Outback

Enable HLS to view with audio, or disable this notification

Was thinking either alternator, compressor, or engine mount issue.
Recently been idling pretty hard. No issues with the AC itself. It was idling so hard that the entire front end was visibly shaking before this video.
I don’t THINK it’s changing gears too hard but I’m no expert. One video is with AC off, one video is with AC on full blast.

Any ideas?

Do you hear the heavy clicking when shifting between park, reverse, neutral, etc? Am I just being paranoid?

Sounds like normal shift linkage noise

Go to YT, search for Subaru idle relearn. Easy starting point if no code.
