Spark Plug Wire: Testing and Inspection
Inspect spark plug wires visually first for any cuts, burns, or damage. While engine is running, inspect for any arcing to ground or other components. Use
a spray bottle to lightly coat the spark plug wires with water while observing idle quality. If idle quality diminishes or engine stalls, spark plug wires
should be replaced.
