Although the problem could be caused by a bad spark plug, that is not the whole story. First of all which engine are we talking about here? The 5.4L V-8 "Triton" engine has coil-on-plug (COP) assemblies, which eliminates spark plug wires, so the idea of replacing spark plug wires on a 5.4L engine is not an issue.If you have a 5.4L V-8 engine, then more likely problem is a bad coil, and it's fairly easy to replace the #5 COP assembly, and related spark plug, since it's located at the front of the engine, on the driver's side. A new COP and plug will cost about $50 at your local auto parts store - try that route, and likely the problem will be resolved.
