    Anyone have opinions on the best stuff to initially loosen the 'stuck' plugs on a 4.6L 3-valve. I was considering either PBBlaster or Aerokroil. Some say regular carb cleaner, but there must be something better.:shrug:

    Ive heard rumors Ford has something they use. Spray down in there before they begin. Probably very similar to PB.
