HI there,
It is possible the piezo resistor is loose inside the sensor.
Frequency is really the telling sign on this, because the sensor picks up vibration, not just engine knock.
So, that being said, you may have a bad sensor.
The key would be to monitor frequency from left to right to determine what is going on.

HI there,
You must make sure that you do NOT DROP IT.
Dropping them ruins them.
And torque is critical to performance.
14 ft lbs I believe.
