This is on my 93 LT1. No exhaust leaks or rattles going on that would be detected as knock but when I log with Datamaster I can see the knock count increasing contantly to the point where the counter roles over and starts again every couple seconds. It's not really causing much retard as I saw a max of 1.1 degress pulled on my drive home today. Anyone seen this? What would cause it to detect knock at such a rate. Bad sensor?
