7.3 turbo Loss of power

I have a 2001 powerstroke 7.3 that had a sudden loss of power. I went to start the truck this morning and it fired up as usual. I was in a hurry and didn't let it warm up for very long before i left work and when i pulled out into the street there was a loud noise, the "Service Engine Soon" light came on and i lost almost all power. The truck continued to run but at a very rough idle and i had no power when i gave it some gas. I am new to owning a diesel and don't know a lot about them. I am open to any suggestions cause i cant afford to take it to the dealership to get fixed.

Thanks Mark

We really need a better description of the noise...

I can't think of anything but a intercooler boot. But like goldie said it still idles fine. I bet you threw the belt. That could throw a code and make the truck run rough. I bet if you popped your hood it's gonna be easy to see.

the belt is still intact and doesn't look like it ever came off. the weird thing is that the "service engine soon" light is on but there are no codes to be found

Nah, I don't see how the wastgate could make a noise like that. Did you check your intercooler boots?
