When I pulled this spark plug it was intact, and had a TON of loose deposits around the threads.
The deposits are light brown and almost the consistency of powder/flour.
I tried to get a photo of it..
I replaced the spark plug, with a random old one, that looked in fine condition. I cleaned it up and placed it in and the truck is running at about 90%.
Still doesn't have the 'umph' it use to have. The torque seems to be pretty low.
Photos were taken on my phone, and NO I did not spray the spark plug area with anything prior to the photo.
