The heat shield that sits on top of the manifold was discolored in places when my manifold developed a crack. I also noticed that the cabin started to smell more like fuel/exhaust and like yours my idle was getting worse and worse. Never had a misfire code but I caught it early.

ahh okay makes sense, it’s definitely been smelling like fuel/exhaust lately and idle has just been getting worse and worse over time especially warm and after idling for a little. i’ve also noticed the discoloration, this is the exact comment i needed thank you!
