9.28.23 Update: Full transparency! Car at cold start this week started to experience a fluctuating idle. What’s weird is after it warms up it seems to drive just fine. Anyhow, I dropped her off at BMW of Alexandria this morning for my mechanic to give it a good one over. I was told the issue is an Intermittent misfire on bank 7 and 8. He’s thinking a faulty O2 or injector. Scans said ignition is fine. My mechanic is the lead tech there - will have the whole shop put a set of eyes on it. Hope to have whatever is wrong fixed soon! Sorry about that (to all potential buyers) but I ain’t selling this car until it’s perfect. Will provide an update when the issue is fixed.

9.30.23 Update: Mechanic fixed the issue. He chased it down to the rear O2 sensors. Sensors weren’t faulty but the drivers side seemed (weirdly) a bit loose. He pulled them out, swapped them, and ran it - smooth idle and no misfires. He then swapped them back and ran it again. Smooth idle and no misfires. So the problem with the fluctuating idle at cold start and bank 7 and 8 misfires is gone. Mechanic genuinely wished swapping O2s would have replicated the issue on the other bank… but his guess is loose or bad connection.

All is well!
