Just looking to see if anyone else might have a suspect to chase. 2020 QX60 with 92K
I thought it was a bad valve cover gasket due to noticing the tube seals allowed oil down the tubes while changing the plugs. Ordered and replaced valve covers to correct. (Funny that when I replaced the valve covers, there was no oil down in the tubes this time, maybe 15k on it after plugs being replaced) but still getting a slight miss during idle. Hasn't cause a CEL on but I still feel it there. Any ideas or info needed let me know.
