Is it possible to test plug wires with multimeter or with another method?
yes, you are testing for resistance. Ohms.
Rule of thumb is resistance should not exceed 5k ohms per inch or 100k ohms total.

Well, I checked the Haynes manual and it doesn't say anything about wire resistance. It says if it is more than 2 years old with 30000 miles, it needs to be replaced. I wonder how many people out there change theirs at every 2 years.
There must be a way to test the wires. I am asking this because I feel slight missing at long stops while idling. It maybe happening while driving as well but I also have engine mount issues so I can't say for sure if it is missing. It may blend in there. Mine car is OBD I so it doesn't flicker the CEL when misfiring occurs. It is hard to detect sometimes. But whatever it is, it is not constant, mostly happens randomly. My plugs brandnew Bosch Platinum +4. Maynot be as good as Motorcraft ones but they should do their job. So if I can just make sure my wires are alright, I will move on.
Get those Bosch +4 plugs out of there. Truly junk. This could be your problem. They don't work well with waste fire ignition systems.
