How do I check Ford spark plug wires?

I have already gotten a little bit of help on this and I have watched a bunch of videos on the subject. However, the more I watch the more confused I get. Our 96 F250 with a 351 gasser runs real rough. I have a suspicion a plug wire(s) is bad. I have a new multimeter but I do not know how to use it. That is one of the problems I am facing. All the videos I have seen use different meters. Where do I set mine? When I do get it set correctly, what numbers do I want to see when testing the wires. Please feel free to break this down to dummy level and a step by step would be nice as well.

And this is the meter I have:

Start at the highest ohms setting 2000k = 2,000,000 ohms and go counter clockwise until the setting is above the amount on the screen but not below.

4,500 = stay on 20k
1,500 = stay on 2k


My guess is you should end up either in the 20k setting or 2k setting. Make sure black probe is on the COM plug and red is in the V/ohm plug. The reason you have multiple ohm settings is the accuracy varies and is indicated in your manual based on the resistance tested. I would estimate the resistance somewhere in the 2000 to 10,000. If it is broken then it will be max, OL or super high value. Something like that on the screen.

Hope that helps,

Wes
