Injector probs after studding

[AvroAero]

I just studded my 04 6.0 and put it back together. After a while of cranking I got it kicking and then it started but it idles and runs rough. If you hit the accel a bit it'll climb and one of the injectors sounds like a dry clack. Best described as putting paper in a fan and having it hit the blades. I also have a p0275 code. I think that injector has gone bad. It also smokes on idle. It's more a grey, than a dark black, but I still think it's just soot.

I have to take the intake mani back off because the weld for the EGR coolant bypass wasn't satisfactory and is leaking, so I'm planning on sticking a new injector in there once I get it off. In the meantime any ideas?

Also starting it, if you let it sit it takes longer to start, it'll turn over with no kicking then once it kicks it starts right up. But if you start it right after turning it off it starts right up. Like it's letting fuel bleed back or something.

I know when you do an injector change out you have to take it for a good drive to purge the air out of the High pressure oil system otherwise it'll take a while to fire up. As for the code. You probably have a dead injector. #5 acoording to the code.

I changed out an injector in my truck a month or so ago. I had to take it for a good drive before it liked to start right up after sitting.

Okay, thanks for the advice. Have the injector in the garage and its going in after dinner. I want my truck back!

I replaced the injector to no avail. I've been trying to diagnose the electrical but haven't gotten very far. What else can this code be indicating?

Also when I'm starting it, it doesn't have a constant speed. it seems to cycle 7 (i'm guessing) cylinders and then one of em its like it has a hard time pulling over. A constant starting rpm then a point of drag, then normal. I'm almost feeling like something in that cylinder was installed wrong as far as valve train. Could a injection problem cause that?

That code could also be caused by a valve train problem or no cylinder pressure. But i would guess something with the valve train. I am no help there though as i have never had the valve train apart on my truck.

Is the valve train mabye out of adjustment? or you leave something in the cylinder? I was at Ford today and they showed me a piston that a bolt got into the cynidler somehow. Looked semi cool.
