So we bought a 1999 Plymouth Voyager 2.4L with 3 speed automatic about 2 years ago. It had 114,500 miles at the time.
Around 125,000 miles it was having intermittent misfire and hesitation. I installed new plug wires and then it ran fine.
Around 129,000 miles the intermittent misfire and hesitation came back. I changed the plugs (used Champion copper) and then it ran fine.
Around 139,000 the intermittent misfire and hesitation came back. I finally took it to a shop and they replaced the plug wires. Now it runs fine.
The wires I bought were Tailor resistor wires. The wires the shop just put on are Federal Pro Series by Standard.
What would make the plug wires fail in only 14,000 miles. They were not mishandled and were not against the exhaust manifold. I did not yank on them or twist them beyond slightly for installing.
