Question about Cars & Trucks
Sounds like a vacuum leak or a bad intake manifold gasket. Take engine cleaner and spray the gasket where the intake manifold bolts onto the motor while running. If there is any change in the idle, your gasket needs to be replaced. Spray all vacuum hoses too. This is the best and cheapest way to test. Let me know how you do please

You never replace anything, on a Wishing,Hoping,Pushing,Poking,diagnostic approach
You learn the vehicles Systems,Test,then Replace,if you have a failed component.

Then you lean O2 Codes will go away.
Not a the plugs.
Think lean---Vacuum leaks,EGR Valve leak,EVAP System leaks,anything with a hose that lets air into the intake system.
Exhaust System leaks,near sensors
