Sometimes I get the white smoke, most times I don't. At least I don't see any. Sometimes it will miss while trying to accel from a stop. It only does this after a long,steady drive. It may be a coincidence but it seems to do it only in high humidity. I go to West Texas or New Mexico, I can't make it do it. Took it to dealer last week. Same crap. Could not duplicate, no codes. He gave me the 800 # to ford and said complain to them. Great customer service said the engineers told them it was a charachteristic of this truck and there was nothing they would do. No help. No buyback. Nothing. Didn't matter that I've had Ford trucks for 20 years. Has anybody been able to fix the no- go problem? Do I put more money into it trying to solve the problem? Will dpf/egr delete fix it? Do I wait until I get run over and let my wife sue ford? Do I bite the bullet and get a lawyer and sue for a safety issue? Safe ton say I will never buy another ford. Thanks for any input.
I don't know how far you have researched this, but I had the EXACT same problem with my 08. They replaced the CAC and that seemed to fix the problem. I know there was aTSB on this several years back.
My problems were just like you described. I would get off the interstate and after coming to a stop and start going again, it would sputter and then start running fine. Trying to pass someone on the interstate was a crap shoot as to whether or not it would fall on it's face. I truly believe humidity played a part in it.
