Anyone know what this could be?
Engine started idling rough and slow to accelerate, making this burbling sound at idle and sounds horrible when accelerating.

one spark plug had a small amount of oil on it.

Changed all four plugs, no real change, pulled coils and one of the four looks totally different, like wasn’t OEM part.
