Once you pull the electrical connector off of the coil pack you will see two metal pins. Put one of the test leads from your multimeter on one pin and the other test lead on the remaining pin and the resistance between the two should be about 0.3 - 1 ohm. If you find an open or the resistance is way off then it is supposed to indicate a bad coil pack. I also had my coil packs unhooked from the plugs and completely off of the truck but I dont know if that matters or not. hope that helps

Ahhh, the wonders of the search function. Change a word and Voila! This'll probably fix mine.
To quote JLangton -"Have you ever changed the spark plugs? I purchased my '98 model with 107K miles on it,and on the test drive it was weak,and would stutter under heavy throttle.Changed the spark plugs(they were the originals),and it ran great after that.Honestly I dunno how it was running before I changed them-there was a .080" gap or more on every plug.

This sounds exactly like what's eatin' mine. Now off to find the spark plug brand threads.......
