Recently acquired a 2012 F250 Super Duty 6.7L diesel. Primarily to travel with a 33’ travel trailer. Love the truck but with the colder weather setting in she sputters when I first start her in the morning - only for about 10 seconds, then isles just fine. Looking for answers.
Welcome. If you can do a youtube video and post a link, would be helpful.
Running rough a few seconds when really cold isn’t bad.
How long did you plug it it?
What is coolant temp when you start it?
