I recently bought a 92 Talon Automatic that had snapped a timing belt. Rebuilt and installed a new head amongst many other things. Engine runs great except heavy heavy knock is bieng picked up.

Engine picks up the knock only after 18-20% throttle (Whch is when I believe the ecu decides to start caring).

It immediatly jumps to 35-43 counts after 20%.

Brand new knock sensor

Verified timing is at 5* BTDC

Verified no boost/vaccum leaks

If anyone has dealt with this issue with any luck Id apprecaite your input.
As of now im going to look for exhaust rattling somewhere as this is obviously phantom knock.
