They changed the sparks and continued with the same symptoms.

Does anyone have an idea of what might cause the engine to fail and not have any errors in the ECU?

That's really annoying and surprising that's there's no fault code.
:-k does the dash cut out when the engine dies?

The problem now isn't to hang up.
The current problem is engine working with rattles and shake.

The dash doesn't turn off, the car continues to work but without force.

Today the coil pack was changed and the car is ok now.
Back on the road

As the problem was misfire due to the coil and there was no error in the ECU, is it possible that the knock sensor is faulty?

Update.
The problem was the ignition coil. The car now works normally.

Almost normal, he continues with hesitation as he accelerates.

I was measuring the voltage of the TPS as you can see in the film and I saw something curious.
The voltage drops when I'm opening the butterfly and goes up again. I don't think it's normal.
