I have a file I grabbed the other day which accumulated quite a few knock counts but it did not show much knock retard. Knock counts accumulated at a rate or 2 or 4 counts at a time, about 100 counts over 7 seconds. Knock retard was only 2 degrees though, and only for a short blip.
The knock ignore was programmed for 3.5 seconds, so it had expired and counts were still accumulating after the expiration.
After the pull, I checked the plugs and they look fine. No evidence of any detonation.
During normal driving, the engine never increments knock count. Shows a typical 6 or 8 counts on startup.
Should I be overly concerned about the counts? Or just take it with a grain of salt and continue to monitor knock retard and watch the spark plugs?
