What causes a weak spark in a spark plug?
Intermittent misfires are often caused by a weak spark or a lean fuel mixture. Click to see full answer. Similarly, it is asked, what causes a weak spark? Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug.

Why do I need to replace my spark plug wire?
The following situations call for immediate replacement of spark plug wires: Vibration damage – Constant wear and tear caused by engine vibration can loosen the electrical connection at the spark plug. This causes an increase in the voltage required to fire the spark plug, which could damage the ignition coil as well as the spark plug wires.
What happens when a spark plug gets cut?
Abrasion damage – When spark plug wires rub against engine parts, particularly sharp edges, it causes cuts and breaks in the insulation. Once this happens, voltage can jump to ground instead of reaching the spark plug. Use the digital multimeter, set to Ohms Ω.
What are the symptoms of bad spark plug wires?
This is necessary due to the aging of the spark plug wires from exposure to extreme temperatures (hot and cold), engine chemicals (oil, grease, coolant, etc.) and electrical stresses. Common signs of failing spark plug wires include a decrease in power, acceleration, and fuel efficiency.

How do you change the spark plug wire?
Before installing the boot on to the spark plug, add a small amount of dielectric grease to the spark plug boot. The boot will be fully seated onto the plug when a small click is felt. Plug wires run from the distributor or coil to the plug, and must be replaced exactly as factory run.
What happens if you pull on a spark plug?
