Our 2024 Expedition MAX Limited does EXACTLY the same thing (very slight miss) and has done so since new (now 430 Miles). It is so infrequent, slight and so quick that you have to be paying attention to be able to notice it! I always attributed this to the 'Automatic stop/start' of the engine at signals and/or pause in movement. It seemed to me the computer was anticipating the 'stop' engine feature. Don't really know, though?
To me this stop/start feature is 'very aggravating', and I wish I could permanently disable it. I know you can disable it by pressing the "A" button on the dash but, this only disables it for ONE (1) start cycle. Once you shut off the engine, the next time you restart the engine, it automatically cancels the "A" button 'off' mode, then requires you to reset the 'off' once again, by pressing the "A" button.
If anyone knows how to Disable this feature permanently, please let me know. I would love to do it to my Expy. On my new 2023 Transit T350 Cargo Van, it said on the window sticker "Auto Stop/Start Removal - NO CHARGE", and does NOT do this Stop/Start ever (thankfully!) I am not worried about this slight miss though. It does NOT seem to have any effect on power or acceleration. Enjoy, Lance
