[QUOTE="Atsah, post: 500405, member: 186"] Get rid of the oiled K&N and go back to stock (stock air filter on a 6.0 works perfect) unless your making big power.. The reason I say this is because not only do they not filter well, they will pull the oil into the tube and on the MAF and cause CEL 's and the tuner should go in the same trash can.. SCT in a 6.0 FWIW.. JMO and most other 6.0 owners opinion.. Any 6.0 I have had did not like leaving the driveway until it was warmed up for a few minutes.. My guess is you have injector spool valve sticktion and or a weak FICM. Make sure your batteries are working properly also.. FICM voltage should be 48V not cranking, cranking and key on.. Could also be a glowplug circuit issue but sticktion and FICM problems are more likely.. What oil do you use? 5W40 synthetic will give you the best cold weather results as I'm sure you have allready read in this thread.. [/QUOTE]
