Hello to all...
I took off the throttle body to clean it and since I don't have an adapter for the bolts I had to remove the coils right in front of it and this is what I found:
The first image is the 3rd spark plug well and the second image is the 4th spark plug well. I found this by accident and the discoloration is concerning.
What does it mean and what do I need to do if anything? Any and all help will be greatly appreciated...
