Hi,

Since a few days ago, I have noted that my M3 does not go up so fast from 7000rpm to 8400rpm and the diagnosis does not show any fault.

Before this I timed the 100-200kph and it was 10.9-11.2 seconds, and now on the same road it reads 11.8-12.0 sec.

Does anyone know what the problem might be? maybe ignition coils? The spark plugs are approximately 12,000km

How could I make a real time log to verify what the failure might be?

Thanks!!
