Tick and rpm skipping? Help!

[SimonD]

We have a similar problem; rpm skips from 1800 to 2000 on Mustang Bullitt 2020….

Turning off each injector shows v little effect with no 6 and 7.

Coming back to the old post to update, I eventually got a new short block under warranty after oil consumption issues and now she's running better than before. I also started the new enginer with full synthetic straight from the dealership and no tick yet.
