Default arcing on 2nd set of wires

I have been having some vibration issues and I am now feeling it more in the front end. I took a look and saw arcing from the boots to the engine and from one wire to the next. I changed the wires with Duralast brand and saw horride performance and even more arcing but this time the arcing was from everywhere. almost all cylinders were arcing one to the brake booster the other would arc to the oil dip stick tube. One cylinders wire was actaully surging from one end to the next with electricity that you could visually see run on the outside of the wire. Now I replaced those with the Bosch brand and the wires are still arcing and the same cylinder is surging in high rpms with electricity. Should I try another brand or start looking at the coil?

Make sure the coil isnt cracked somewhere.I doubt you got three sets of poorly insulated plugwires

Yeah, given what you've said I would think about changing the ignition coil where all the wires connect. Makes sense why all the wires would act up

I had this issue once. I bought a set of accel 8.8 wires and it solved my problem.
