Rough idle after sitting for a few minutes

[Woolaroc]

I've been noticing for the past several months that if I sit idling after a few minutes it becomes a little rough and there is a shutter/shake that begins. It's fine for about 3-5 minutes and then kicks in. Anyone else have this?

I also have a stumble. I logged “misfire” on my Accessport and they didn’t correlate. I’m wondering if it’s engine mounts?

Anyone replace those?

If you have quite a few miles on the truck, pull the Intake sensor on the top rear portion of the intake manifold. You can see it behind the intake cover. My '19 was doing the same thing and I pulled and cleaned all of the intake sensors with sensor cleaner. The one on the back of the manifold had a good bit of oily residue on it. This solved the problem for my truck.

thanks I'll try that!
