Power/Idle drops and cut off

Interesting write-up of the issue and your efforts. Though, that’ll be cold comfort to you right now.

I think your first post comment regarding one bank and fuel starvation/flow issues is where this is headed?

Good luck for a straightforward outcome.

Quick update.

Ever since that small shut off, during the first drive after the FDPM swap, the car has been solid. I've had it on several chunky journeys in both traffic and on motorway, it's been spot on.
I have a feeling that the shut off after the FDPM swap might have been the main PCM catching up, now it's cycled, it seems to be working just fine... fingers crossed
