Phantom knock issue

[turbotalon1g]

I usually just go a bit over hand tight with a wrench.

Verified location, good, lightly snugged the sensor, no differance. Found a small exhaust leak at the flex pipe, think this would cause it?

Things Ive tried

Moved spark plug wires away from each other to verify there is no spark jumping, no differance.

Temp fix exhaust leak at downpipe, no differance.

Removed damper pulley and ran to find no differance.

Seems to occur only when slightly warm and warmer (dont know if its just the ecu ignoring it earlier) and when you blip the throttle past 18%, even in nuetral with no load. If you hold it steady past that it does not register any knock.

Problems appears to be affected by load more than engine speed. Blipping the throttle to 20% the knock counts will hit a random number between 10-23 then back down as I hold it at 20% throttle. If I put the transmission into gear and hold the throttle at 20% and put a load on the engine, the knock counts will peg at 43 and stay there.
