Good morning all

I have the check engine like on when I press the M buttom in power mode. The light shows "engine reduce power" and of course, it feels a lot slower than in regular mode. Regular mode seems OK.

What cause that?? I seems the engine reduce the timing a lot.

Can somebody tell me what to do on my case?

Thanks in advance!!
