03 6.0L: Coking
all,
according to the dealer ship the turbo/intake manifold / EGR valve is built up with carbon deposits. They say to run the truck on the highway and try to burn it up. Is there some type of additive to add or does anyone have some adivce to clean the components. Ford says the process is about 2k +.

to repair it correctly will require cleaning the intake off the engine.
you can try pm22 fuel additive from ford.
this concern is mostly casued by:
1 poor fuel quality
2 high idle times
3 lack of maintance

what would cause high idle times? Do you mean leaving the truck idling for along period? Also, I pretty much take care of maintenance. I change the oil every 3 to 5k miles, replace air filter as needed, and I am about to change the FICM / Fuel filter. I also run Stanadyne fuel additive almost every other fill up. I dont run my truck every day because I have a commuter car for work. The dealer wants around $2k to do the cleaning and suggested to run the truck. The ICP sensor / pigtail has been replaced due to P2258 code. I wanted to change the EGR valve but they suggested runnng the truck.

Short answer yes.
Consider doing the egr valve cleaning yourself.
After the cleaning - it is common to have carbon particle dislodge and then jam the EGR valve, or the intake and exhaust valves and code.
It would be a P0405 code...
Don't sweat it, just turn the code off, log it and keep going.
Spirited driving (max turbo boost etc.) will get you the code again as more particles are dislodged.
With a really plugged intake, unless you are doing cheezit style remove and clean thoroughly, you can be getting codes for a while.
If there is nothing else wrong with it --- ignore it and keep going after resetting it.
If you are insistent on no codes -
A) do the through job
Get a Scantool and reset it to not give signal..
B) delete EGR
C) stealth delete
D) unplug EGR Valve.
