Help identifying this popcorn noise (08 Expo 5.4)
Sometimes does it at idle and almost always does it a low speed. It sounds like metallic popcorn, and I haven't had any luck identifying the source of the sound on my own. 08 Expedition King Ranch 5.4 Triton with 130,000 miles. No noticeable change in performance. Hopefully someone has heard...- joshdosmil
