Went To Start My 2001 Supercrew And Its Skipping, But The Check Engine Light Is Not On, Why Is That .there Is Radio Interference On The Am Band. Can A Scanner Pickup Witch Cylinder Is Not Firing ? It Was Recently Wet And Then Got Cold Does Ford Coilpacks After Years Of Age Fail Due To The Weather?

 

Time to replace them - Do the plugs as well . Make sure you use Motorcraft plugs and plenty of Dielectric grease.

Heres the coils you want for your COP's system.

^Agreed, ya, especially when they get wet, it often helps them f up. In reality, like old plug wires and caps etc, they get weak over time. After you replace them you'll be experiencing a new truck again.
