I am experiencing some hesitation under acceleration.
I am going to start by giving the car a tune up..since it hasn't had one.
1) How do I test the spark plug wires?
2) How do I test the coil packs?
With the mileage you have on the car now, you might as well just change the plug wires. The wires are 7 years old, and the wire insulation can break down and cause issues when wet out. Check the coil pack by spraying it with water using a spray bottle. Look for an electrical light show or rough running after spraying. In that case, replace the coil. Just get some Motorcraft plugs and wires, what the car came with.
