Rough Idle 1500 Limited 2022 at times at start and while in drive at stopped

[Leftyvaquero]

Afternoon, has anyone here experienced a rough idle at start or while in drive at stopped in traffic? Not all the time occasionally, truck is a 2022 1500 Limited with E torque 21,000 miles.

Yes, I'm going through it now on a 2023 1500 5.7 eTorque with 36K miles. I started experiencing the issue shortly after purchase with engine cold, start/stop off, and truck in gear. Sitting a stop light the truck would have a rough idle where it felt like it was starved for fuel. It took three times taking it back to the dealership for them to identify that cylinder 6 had high misfire counts with no check engine light. They ended up replacing all lifters on that head. After getting it back, I noticed a rough idle on startup when cold while in park. After starting and let it warm up, once the RPMs drop to 580 RPM the idle gets rough again. My scanner was showing 22 misfire counts on cylinder 6 in the matter of a minute with a few misfires on other cylinders. It's currently back at the dealership as of today and waiting on a response as to what their conclusion is.
