Load knock and load of Black Smoke at Idle

So my brother in laws 04 has a bad knock, real bad with a crap ton of black smoke at idle, Codes 0483, 2509, 0088. I know what the codes are but what is going on. Is it a bad injector? I really don't want to run it no more then we need to. But I have a feeling that we are going to need a starscan to figure out more on what is going on. Any advice would be great. Oh, if it is just an injector, how do you pin point without a star scan? do you just unhook each injector until that bad knock clears up.

, on the title I said Load Knock, meant to say Loud Knock
