2002 GT, trying to diagnose a top-end tap, which most likely is a lifter issue. I was unplugging injectors one by one and when I unplug the #1 injector (front passenger), I get a rod knocking, unplugging the other injectors cause no dramatic effect, just the slight idle stumble one would expect. So what's going on here, do I need bearings? Do I need a Coyote crate engine?

Let me be clearer.

All 8 injectors plugged in, no knock.
Unplug any injector other than the front passenger, no knock, nothing really happens.
Unplug front passenger injector, knock, whether it's fuel or something else, idk.
Unplug COP and injector, no knock but rough idle (to be expected).

Try posting this issue in the genral talk section of the 96-2004 forum. You have it posted correctly, but more people will see it as a general post. Hopefully someone can help you out.
