Question about coil pack

[Brutus]

Does anyone know what reading is right checking my coil packs on an Ohm reader/gauge?
If one of my coil packs is starting to take a dump, should I be getting a CEL?

Thanks.

My .02...I was having shuddering issues with my 96 3.4....I have 157k...I went to the dealer and he said the check engine light is only for emission components...that does not sound right but oh well...the primary ohm when cold is like .65-1.02 and the secondary (which I could not get to test) is 9.3 - 16.0 cold they are both a bit higher when hot...hope that helps! FYI I put new wires on and my plugs were WAYYYYYY worn out...with thoses 2 items it runs perfect now!

Check them all. If you find one different than the rest, that would be your huckleberry.
