David,
Good explanation. My problem is that I have damaged hearing and cannot
detect the ping of pre-detonation from other engine noises, although I
do know what it is suppposed to sound like!
However, my car does tend to run on a bit when warmed up (not
overheated).
Does this also always indicate over-advanced ignition?
