rough idle when temp under -30
Everytime I start my 2011 f250 6.2, with ambient temperature at -30 or colder. I get an extremely rough idle for roughly 10 to 30 seconds in length. Sounds like it is running on only 4 cylinders, then you I will hear a popping noise and it idles normally after that. My guess is an exhaust restriction of some sort, maybe egr valve related. It never throws a code during or after the rough idle. Also doesn't matter if its plugged in or not. Any ideas? Also truck has roughly 100k miles on it.
