Truck just threw this code, looks like cylinder 1 deactivation. Related to the eco mode crap.
My truck is still under warranty but curious if anyone else has had this issue. I had planned on getting a programmer when I was out of warranty and disable the eco junk anyway.

I haven't had that issue, but if you hate the MDS system and haven't gotten a tuner yet, you can turn it off by using the gear limit buttons on the steering wheel.
Truck has to be in drive.
Press the minus button once
Press the plus button until the display on your gauge cluster reads 8
Doing this disables the MDS system until the truck is taken out of Drive.
