non-reactive knock sensor????
Is it possible to have a dead knock sensor that just can't "hear" any knocking so the timing is never set back?
Reason I ask this is that I got a tank of bad gas a few weeks ago, I think the gas tanker-truck person put 87 octane in the 91 octane tanks. Needless to say, my max was knocking pretty good. It went away as soon as I filled up at another gas station with 91 octane.
Wouldn't a properly working knock sensor retard the timing before the human ear could hear engine knocking if 87 octane was accidently used?
BTW, I checked for codes...no MIL on and no ghost codes.
