I thought it might be cheap gas so I filled up with premium before heading to the coast and burned through it. Filled up and did it again. I got 22 mpg on those tanks so it ran fine. Just the idle.
The direct injected engines have a tendency to build carbon on top of the valves, could be the cause of a rough idle. Whether it actually is or not, it cannot hurt to do a "top engine clean" or "fuel induction service" regularly. If you have somebody with the right equipment they can monitor any misfires, it may be slight but not enough to set a code.

I liked the look and would like to do something similar to this one.
Have done several 2" level kits on these. Seems like they need another 1" in the rear unless you go with 1.5" front. I have also removed three due to popping in the front steering rack caused by excess inner tie rod angle. 285's fit nice on them.

By the way, NICE TRUCK!
