2016 Chevrolet Silverado 2500HD - Intermittently Loses Power

occasionally engine idles at about 850 rpm and truck has lack of power and gas mileage drops

Is this a gas or diesel?

I had that problem on an old 1985 Cadillac 4.1 and the replacement computer cost me $100. Oh well. I hope yours can be diagnosed for free under warranty. Nothing like the old solid state electronics.


Thank You

@cdaquila a little help here, please.

how often does this occur?

Are you aware of when your truck is doing a regeneration, and cleaning the soot out of the DPF filter? Could this be what is going on?

It looks like if you dont get out on the highway enough this could be a problem.
