As I was driving this morning my00 gc8 all of a sudden felt like it cut off, engine still running and did not stall but I couldn't get it to go over 2k rpm.
I pulled over, turned off engine, started it back up and it was the same thing.
I turned it off and waited for a few minutes before starting it and it was fine again.
I continued driving to work but off boost and kept it under 3k rpm.
Would I be right in saying that the car went into limp mode? The car has been running fine up until today.
Is there a way to check if the afm is still in good condition? I remember reading somewhere - you start the car, remove the afm plug and it should stall to know if afm is still working (or should the engine continue running) - can't remember which?
