Do our wagoneers have MDS? Where the engine deactivates 4 cylinders for better gas mileage? I never feel it like my other hemis.

When I have the center cluster set to the mileage graph is shows when the engine is only running on 4 cylinders. I do not notice any hesitation when it shifts back and forth. Mine does not seem to have the auto start/stop feature. Engine never shuts off when stopped. Also does not have the button to shut off auto s/s on the center console. GWIII.

So you have a 392. Im referring to the 5.7 hemi with etorqe.

Yes the 5.7L has cylinder deactivation and auto stop/start. For the Wagoneer they have upgraded engine mounts to reduce vibration.
