Grahame,
Great post. Keep up the good work. We now know why Honda is placing knock
sensors on their cars. They must have received thousands of complaints
from Honda owners in the 1980s and early 1990s that had knocking and
pinging problems. The knock sensors were the solution to the problem.
However, if the timing is off or the knock sensor is broken--pinging and
knocking problems happen.
