I often have asked this question... how can I tell or does any one know if
the knock sensor has detected and backed off timing?

Some say knock sensors only are in use above 3k rpm. My two automatics,
(90 and 91 100's) rarely go above 3k rpm and use 87octane always.  With me
driving and running premium or using premium on the hiway shows no mpg
gain.

I use premium in my '90 200 tqa but would still like to know if it ever
knocks. I have never got a code but I understand it can knock and make a
code.

Comments?
Nick
