Engine surging in mornings

[ruggerag]

Is this normal? Every morning when I start my truck it surges for about a half mile or so, while I drive 15-20, until I get out of the neighborhood and onto a street. It doesn't happen any other time. It isn't searching gears, it just doesn't want to stay at one speed until I get it warmed up.

I have never experienced what you're describing in my 2015 or anything else except vehicles with VERY large cams.

Doesn't sound right. Even my Hellcat doesn't do that.

I just posted a new thread about this same issue. Check out my thread at the top of this section. Let me know if that sounds like the same issue you're having.

Mine does this too, barely noticeable.

That's the thread I just started. You guys can take a look there and let me know if any of those symptoms occur on your trucks

I have this exact same issue in my 2015 Sierra with around 800 miles on it. Only happens after the trucks been sitting for longer than a few hours (on my way to work and when I'm leaving). I'm typically in first gear and traveling less than 20 MPH.
