How do you know if your knock sensor has the car in limp mode? (is limp mode significant on our cars or just mildly reduction of power)? Also i've read that the AFM's are sensitive and prone to problems, what problems and how do u knwo if the AFM is bad?

That's what the CEL and the diagnostic system is for!

Safe mode is a limited dirveability/limited performance condition. I twill have a noticeable effect on performance. But so do a lot of other problems.

1) If you don't have a CEL staying on or coming on intermitantly, you re NOT in safe mode.

2) If you are getting a CEL, the diagnostic system will tell you why.
