18 Hours on my first plug change!!!

COPs fail from lack of initial quality, heat, age and the cumulative stresses of high voltage.
Winding typical short internally due to insulation breakdown between windings. This leads to reduced ( and eventually no ) voltage production.
Measuring resistance will only tell you if they are open or a dead short. To test them properly requires equipment you do not have. They need to be tested under load.
Most folks advocate using quality COPs like Motorcraft or Visteon to mitigate the problems in the first place.
And as importantly - the use of new boots, springs and dielectric.
Good luck.

Unless yer on a strict budget, I always advocate using new boots & springs to complete the job. And you MUST use dielectric or risk misfires.
As fer quality - the OEM Motorcrafts are great - Tasca has great pricing. Or head to Napa and pick up Belden boots (they come with springs).
These things are ~ $5 -$6 each.
G'luck!

I know a lot of people advocate replacing the boots and for $5 each, it's not a bad recommendation. However I had a shudder in my truck several weeks ago but it didn't throw a code. I ended up pulling all my coils off and removing the boots and springs. I simply washed my boots in warm soapy water and dried them. They still appeared to be in perfect shape to me. The springs also looked fine, but I removed all of them from the coils and installed them again a couple times just to make sure I had a clean connection. I then put some fresh dialectic grease back on them and put the coils back on. So far so good. The shudder didn't come back. So, if you're cheap like me it might be worth a try. Only cost me an hour to remove, clean and put back on. Just a thought.

Some folks find their boots have hardened and lost their 'elasticity'. In those cases, the boot will not seal properly on the plug ceramic. Further - minute, unseen pinholes, cracking, carbon tracking etc needs close scrutiny.
I can, however, fully understand budgetary constraints.

Good advice, Rick.

Thanks Summers, Rick, and MGD! I successfully completed the install of the new boots and springs as well as the plugs... I ended up using NGK Iridium plugs with NGK boots and springs, I cleaned the coil terminals real good with a nail file my wife donated to the cause, blasted the plug pit with air before removing them, and put her all back together... All in all, it only took me about five hours, but it really didn't seem that long. The real biotch coils were the 3rd one back on the passenger side and the 1st and 4th on the driver's side... In addition, which I forgt to mention, I swapped my alternator with a 130amp alternator and a larger gauge wire yesterday, I did that first, took about 3 hours just for that... So again, thank you guys for helping me not **** this up!!
