Could be the DI, black DI's are not all sudden death.
pull the plugs, read them, regap or replace
any water in the spark plug well?
blow or vac the plug well first to keep dirt out of cylinders
clean injectors, techron concentrate suggested
if the above does not help, you might need to clean the TB
and missing is missing and the pimary concern is the plugs and ignition as always, idle speed excursions are probably a simple reaction to the missing and near stalls
do not drive with continual missing as you will destroy the cat converter $$$
If you can swap in a black or red DI for a test, the results would be valuable. Your miles are low, but some components age from years as much as distance.
