loud clatter noise at 1500 rpm's, no power, and white smoke on start-up

[armyvet26]

How's it going yall, I have a problem and I am knew here so bear with me please while I try to explain this to you and I am confident yall can help me. I have a 2001 7.3 powerstroke and I absolutely love this truck. I have a 6.4 too, but it doesn't have all the bells and whistles that the '01 has. Anyways to the problem, I had three injectors drop out on me a couple weeks ago and had ford replace them. They re-did the CCT and found that one of the ones they replaced (#8) was dropping out again. They called me back in and told me that they fixed the problem by putting an aftermarket CPS in, which I guess throws the #8 failure. Everything was going fine until recently it has started puff white smoke at start-up and it has a really loud clatter sound, I would venture to say that it is louder than a 12v cummins, I had one too so I know it is louder than that. Here's the wierd part too, it goes away past 2000 rpm's and starts around 1500. i don't know what the hell is wrong with this thing. It has no low end power whatsoever. I have to floor it to get it to go anywhere quickly. Now, I'm not sure if maybe I am just used to my 6.4, or if there is something really wrong with this truck. I hope it isnt serious, because i love this truck. Any Ideas fellas?

Also, I found something wierd in the fuel bowl, it was like gold flakes or something, but I know there is no injection pump on these trucks, so I'm sure it is unrelated. Thank you so much for the help.

Could the ICP sensor be doing all this too?
