Hope this helps someone out there because i was lost and replaced a lot of parts chasing this issue

Did you have any symptoms with your brake?
I have a similar issue where I got the drivetrain malfunction/check engine light and the car lost power. I've just replaced coils/plugs about 3K miles prior so I was confident it wasn't that. However, the hesitation/loss of power felt similar. Then the next day when I connected an OBD II scanner, no error codes and then the DTM/CEL went away and the car drove fine...
Of course I am not at ease knowing something is brewing without any CEL anymore.
