if you 'push' your engine (i.e. WOT, or to Redline), it will misfire, stutter, and engine light will come on.

drive like a granny and your engine may not know it needs carbon cleaning.

What symptoms did you have?

I know about how to clean it via walnut blasting.

I mainly would like to know from others what issues you had.
Not sure if this only applies to n54s only.

Thx in advance
