@CoronaRaptor I am no expert either but I think it may have a catalyic converter issue. I am not too sure. Or it could possibly be a fuse but then it should not fix itself after restarting? I am just so lost.
Usually a code is thrown when there's a cat problem, you'll get it fixed, it's still under warranty.

Could be a plug not getting the right gap/contact- maybe a 2nd start helps the plug “warm up” & “bridge the gap” so to speak....

@Badgertits I see, do you know what kind of plugs that could possibly be? like maybe fuel pump? or anything?

i mean the spark plugs

these engines like fresh plugs every 10k is a good interval if you’re OCD

go w/ a colder plug, I forget the part # they were changed recently, but MPT & other vendors sell em

So this popped up today with a CEL. The CEL did go away after 3 times of restarting the truck which seems really odd to me. Any ideas if this is connected to a muffler replacement? I do not want to deal with dealership bs with how this could possibly be a fault on my part because of a muffler replacement i did.
