on start up when cold truck knocks like crazy just like my other truck when an injector went. some white smoke, mix with hint of black at first, then just white, strong diesel smell. truck runns pretty good when warm. had the local shop(not ford) through it on a scanner and it past buzz test. did have some codes:
low boost(has showed up three times)
#8 gp circut failure(but that is the first time that has showed and truck has done this sence i got it, and truck starts great and its been 10 or colder here)
Fuel injector control mod. (has showed up twice)


Thanks Scott

take it to the dealer and have it reprogrammed, that fixes 99% of rought cold starts. as for the codes, sounds like a sticky turbo and maybe wiring issue for the ficm and gp or a bad gp.

I had been having the same problem for quite some time now... I took it to the dealer last week and they reprogrammed and it starts perfect now...

Mine used to be the same way...it ran like crap when I first cranked it in the morning. Got the latest flash and it runs fine now.
