Another follow up,
Checked the LTFT values today after some freeway driving. Looking at +15.6% and +14.7%. I either have a vacuum leak somewhere (intake boots?) or the MAF is done. Ordered a smoke machine off Amazon, I’ll update after the smoke test.
In other news, I test drove a 2012 Panamera yesterday. It actually shakes more at idle than my current situation. So maybe I’m in the clear on the vibrations. Another thing I noticed is that the vibrations are about 2-3x as bad with the A/C compressor engaged. Without it, it’s far less noticeable.
