Just joined the club with an 03 F250/6.0 engine. Bought it to pull our RV trailer. First cold night we had I noticed that it ran rough and smoked when I started it. Took it to the Ford House where they of course replaced number 6 injector. Still does the same thing, so on cold nights I plug the warmer up and it seems to help. One mechanic told me to change the oil and put 13 quarts of oil and two quarts of mercon trans fluid in it. He said the trans fluid will act like a solvent to clean the oil from injector spools. This should help the problem. Has anyone else heard of this or should I just take my 9mm and shoot now to take it out of its misery!!!!!!!!
