Wagoneer check engine light code

[bienvenido91]

Just hit 900 miles on my Wagoneer and the check engine light starts causing me headache. Getting terrible gas mileage and there's a crazy lag between hitting the gas and the engine actually responding. Thinking it might be misfiring cylinders, but could this be turbo lag too? Local dealer is booked, but can Wagoneer client services help diagnose this?

I'm having the same issue with my car, and it's been 3months since I brought it to the dealership. Unfortunately, they haven't yet pinpointed the cause.

Did you try having a software update done? Maybe that could fix it.
