Since this is a common problem with the 5.4 engine Ford needs to come up with a fix for this ASAP.

problem #1

May 292009

F-150 XL 4.6L V8

  • Automatic transmission
  • 42,000 miles

This appears to be a known problem with the aluminum head, which only has 3 threads in some cylinders, which is not enough to keep the spark plug from ejecting.
