i can read that it says it should be 5.5 k-ohm' s. Im pretty sure that i have it on that thanks.
When i put the mm to ohms i set it to what though?
I get nothing when i switch the settings in the ohms from 200, 2k, 20k, 2m, 20m. Just a 0.L with the prods in place.
Now what?

ohming out a cop wont tell you ####, very rarely if ever does the primary coil fail. they either need to be stress tested by ford or just flat out replaced if you are having an issue

Id like to know how to test them so i guess ill just need to put them on a working motor and just see if it throws a code. Id like to know how else to test so i can start pulling them off wreckers and testing them before i sell/use them. Thanks Guys

the only real way to tell if you have a good coil is to stress test each one, the 10,000$ ford testing equipment works good for this.......

You sure can ohm out a bad cop. I do it all the time. You put one lead on the + terminal of the connector and the other goes to the lead that goes to the spark plug.

There are some cases when the missfire is caused by a crack in the coil boot so you should make sure the boots look ok too.
