Swapped the engine control modules with a 2017 Toyota 86 unit and identical behavior. Not the ECM.

I took out the ignition coils again to confirm and they are definitely not firing in the correct order.

A friend linked me to a TSB that has a lot of similarities. Trouble starting, rough idle. https://static.nhtsa.gov/odi/tsbs/20...67832-0699.pdf

Additionally, I did replace my timing cover which holds the camshaft position sensors…maybe?
