It would be better to let us know the year and model of your expedition so that others might join in regarding about your trouble and let you know how to fix it. You need to let us know if there are trouble codes showing.
Now , since you know the word "resistance", it might be a good idea for you to use a DMM, do a "BENCH TEST", check the primary coil resistance and the secondary resistance for you to be able to see the readings itself.

No problem my friend, it is a misfire on those cylinders, might be a bad plugs, or the coip itself, since you replaced the plugs then it might be the coil.
Might be a good idea to take it to the dealer if it still has warranty.
