weel it's been 10 days since i last posted.
update: The mechanic has replaced timing chain guides
all four tensioners
oil pump
camshaft pulley
truck ran fine for 5 min then rough.
ran codes, got cam position senser & int camshaft position advance
put new sensors & truck ran fine for 5 min then would not hold rpm & got same codes again. opened everything, checked timing, camshaft gear everything looks good, still getting same codes, engine still running ruff.
my mechanic is now at a loss. Anyone have any advice?

Those codes are screaming the timing is wrong! Did you put new chains and line up the links to the marks? how did you set the timing?

the mechanic says he has checked the timing three times and has replaced the timing chains. Thanks for responding!

Is he shure the engine was at TDC when he did the sprockets and phasers. 5 minutes is about the time it would take to warm the engine and the emissions system / computer go to a closed loop operation. Sounds like the timing is of just a hair, ie 1 or 2 teeth.

Thanks for all replies!
Talked to mechanic. he said he has checked timing four different times. (set to 0)
Ran the truck, got to 70 mpg but would not hold rpm.
ran the codes and got cam shaft sensor, cam shaft position advance.
Changed the cam shaft gear, cam shaft sensor and advanced timing cellanoid.
Now the truck won't start and has blown the starter.
He says the truck acts like the timing is off, but it's good.
Anyone know if it could be the crank shaft sensor, or wire harness.
Trucks been in the shop for three weeks now.
All help is greatly appreciated!

Thanks for all your posts!
Went to mechanics shop today and saw the timing, marks are dead on.
Engine starts and runs on bank1, bank 2 is not running.
pulled code from computer(p0027 cam shaft position advance)
went and talked to a mechanic at the ford dealership. thier computer said to replace crank shaft and crank shaft celliniod.
Already been replaced.
mechanic at dealorship is at a loss also.
Does anyone know if this could be electrical?
Talked to another mechanic who said i might try replacing the wire harness. Anyone have any thoughts on this?
Thanks for everyones help and advice!

I usually do not post if I can not help, but wanted to let you know I at least re-read it all.
Judging from what you are saying, it could be electronic.
Im concerned that so much was replaced so we will not know the cause and without seeing it is almost impossible to tell.

if you can provide any more info let me know, I will hit the books and try to find you an answer.
