Also check the timing with the knock sensor unplugged like was said at an idle you should get 20+ and off the scale at around 2500-3000 rpm. If the timing advances when you unplug the knock sensor it could be bad or loose they are picky on how much you need to torque it or it sends a false signal to the computer telling it to retard the timing too soon.
