New to the forum. Have read a lot of threads in the last couple days on the #3 misfire.
i have a 2016 1500 laramie 4x4 crew cab with 208k miles (all stock other than small lift and bigger Toyo M/Ts) and got the #3 cylinder misfire. Of course suspected coil/plugs. Changed them, still misfiring. Moved new coil to #1 cylinder, still misfiring. Last night decided to pull the valve cover hoping for a broke valve spring. Did not find what I was hoping for, instead after pulling fuel pump fuse to spin engine over watched the travel of the intake pushrod on #3 compared to the other intake valves and observed what I was hoping (like many others i assume) not to see, the travel was a lot less on #3. So I guess i have the wiped lobe from a lifter roller failure. Got more miles than a lot of people, so i guess that was good.
The confusing part is, I purchased the truck with 50k and have never seen the ECO light until this issue with the misfire began. I had a 13 ram 1500 5.7 prior and saw the light daily traveling to and from work and assumed this truck didn't have it.
Any ideas on why it would show up 160k miles later when the misfire began?
