I'm in need of a diagram on how to reach and replace the spark plugs on my 1999 ford expedition
4WD XLT V8 5.4 litre SOHC engine. Specifically what
parts I need to remove to get the spark plugs.

Do you know what the coil packs are? They are below the fuel rail. They are black and have two wires going to each one. Every cylender has one, and to get to the spark plug, you must remove the coil pack. There is only one bolt holding each one in place. I can't remember the size, but they may be 10mm.

Let me know if this helps or if you have other questions.
