A '97 f150 4.6 does use plug wires. Are the wires on it the originals? If they are, it's definitely time for replacement. If you have already replaced them, did you use Motorcraft brand? Fords are known to be picky about ignition-related parts being Motorcraft. Also, if the plugs and coils are original, it's best to replace them as well.

For a quick check of the wires, I spray a light mist of water, using a spray bottle, on the wires, from plugs to cap. This will allow you to see any arcing. Feel the wires for stiffness/brittleness of the insulation. Otherwise, an inexpensive plug wire tester, purchased from an auto parts store, can help you test your wires. If you have a timing light, you can hook it up to each wire in turn and test that way as well. Or, use a voltmeter to check the resistance of the wires, they should have a resistance of less than 7000 ohms per foot of wire length. HTH.

The answer you got in reguard to checking the spark plug wires will not apply to any of the Ford Triton engines (4.6LV8 5.4LV8 6.8LV10) as they do not have the wires. Each of these engines have individual coils for each cylinder. They will be located on top of the engine under the fuel rails w/ intake plenum in between. R.W.

They are bad most of the time to go bad down inside the heads. Water gets in it and causes th ewires and plugs to go bad. If you are haveing a missfire problem, replace plugs and wires.

If they are 9 years old they probably are and you should get some new wires but they were not faulty when they were new.

I dont understand the question.
If the wires need replacing you can still find them and replace them.
