duramax guy needs power stoke help
My buddy has a 2000 7.3 if he takes off first thing in the morning the truck will run rough, stall then start very hard once truck warms up its fine for the rest of the day. If he lets it warm up for 10 to 15 minutes in the morning the truck won't do it and will run fine.
my 6.9 needs about 5 minutes idleing then about a minute down the road and its great on a cold morning. however havent had it long enough to run it through the snowy months but you should definitely let it warm up
Your idle might be set too low.




. My old psd HATED cold mornings. Diesels are completely different animals when its stark cold.
