'06 6.0 running really rough in the morning
I have an '06 6.0 with 160,000miles. Mods include bulletproof EGR and external oil cooler. Flashpac tuner always on economy tune unless towing. 5" straight exhaust. It started a few weeks ago running a little rough in the morning, but cleared up after a few minutes. I just did a fresh oil and filter change and fuel filter change. And now it is running even more rough when cold. It takes 15 min of idoling to get to temp(160 degrees ) before it wants to move. Any thoughts before I take it to the stealer... I mean dealer. Thanks for the help.
In an ideal world I would have all ten fingers on my left hand, leaving my right hand a permanent fist for punching...
