What is the best method for replacing a set of plug wires?
Replace the entire set one wire at a time. Start with the longest wire and end with the shortest. Changing one wire at a time will reduce the risk of mixing up the firing order. The plug wires must be installed correctly so ignition timing will be correct. The wiring should also re rout the same as the originals to avoid ?crossfire? problems. Crossfire may occur when wires are positioned parallel to each other. The magnetic field that surrounds a wire when currents pass through it may induce current in an adjacent wire, unless the wires are separated by sufficient distance or crisscross to prevent this from happening. Also wires must be supported by looms or clips and positioned so they do not touch hot exhaust manifolds or rub against sharp edges.
