>From memory: there should be no knock at idle.  Tap on the block or
exhaust manifold near the knock sensor and it should register knock.  If
it doesn't, remove the knock sensor connector and jumper to +12.  That
should make the ESC module signal knock.  If that works the knock sensor
is dead.  If it doesn't the ESC module is dead.  Unless it's a
wire/connector issue, which is most likely.
