I am having rough idle issues and need to check the wires to make they are still good.

For your vehicle here is what they have for specification.

1-15 in. .................... 3000/10,000 ohms
    15-25 in. .................... 4000/15,000 ohms
    25-35 in. .................... 6000/20,000 ohms
    OVER 35 in. .................... 8000/25,000 ohms

Also inspect insulation for any damage. Spray some water with a spray bottle as well around the wires to check for arching.
