Most common is the #8 injector, which is a LL injector designed to try and quiet the idle knock due to the dead head fuel rail on the driver's side.
Also you'll hear split shots from time to time develop a knock or a ping sound at idle. I have that on either the #2 or #4 injector (can't quite tell which one for sure), and I've noticed that it comes and goes. Everything runs fine and it passes all diagnostic tests, but the noise is there much of the time it's idling.
