What is the Ignition Cable (Spark plug wires) all about?

The ignition cables, also known as “spark plug wires” are part of the ignition system. They transfer the spark from the distributor or ignition coil to spark plugs that ignite the air-fuel mixture, starting the engine.

Over time, the cables can get weak and break down. This will make it harder for the spark to reach the engine cylinders, resulting in engine misfires. The car may not start at all. If one of the spark plugs has gone bad, the car will still start and run, but it will run poorly.

Keep in mind:

  • Ignition cable failure is often caused by other failing pieces in the ignition system; a mechanic should check for any other malfunctioning parts, and replace any parts of the system that don’t work.
  • Every time the ignition cables are replaced, the spark plugs should be inspected.
  • Leaking oil or coolant can cause ignition wire failure. If this is the case, the cause of the leak should be repaired or replaced, or else the new ignition wires will quickly be damaged as well.

How it's done:

  • Scan the computer system in the car for codes.
  • Inspect ignition cables (look for white spots).
  • Ohm test on individual cables.
  • Remove and replace the cables if found faulty.
  • Inspect the spark plugs.
  • Clear the codes.

Our recommendation:

Ignition wires should be replaced at least every 60,000 miles, but whenever your car is serviced, it’s a good idea to have the entire ignition system inspected. Any time that you have spark plugs replaced, it’s a good idea to have the ignition wires replaced as well. If you notice that your engine is running poorly, you should schedule an inspection.

What common symptoms indicate you may need to replace the Ignition Cable (Spark plug wires)?

  • Check Engine light is on.
  • Engine misfires.
  • Poor gas mileage.
  • Engine may shake (light vibration).

How important is this service?

The fuel in your automobile is ignited by a spark. This starts with the ignition coil, which transforms low voltage power into extremely high voltage. This high voltage is transferred through the ignition cables, and to the spark plug, where a spark is created that ignites the engine’s fuel, and powers the engine.

When one or more ignition cables fail, this voltage will not be transferred from the ignition coil to the spark plugs, and the fuel will not be ignited. Depending on how many of your ignition cables malfunction, your car will either run poorly, or won’t run at all.

Chris was great, he helped me with my Lexus and changed the bank 2 oxygen sensor which was very difficult to get to because you had to move the seat back. He was fast and courteous and I would definitely recommend him to anyone!

Lexus IS300 L6-3.0L - Oil Change - San Jose, California
Rick was great. He called me to let me know he was slightly behind, and it didn't bother me at all. It was a late Saturday morning and I was just grateful the guy was even working. I ordered a synthetic oil change that came with a tire rotation. I think Rick was only going to do the oil change, so be sure to tell your mechanic you ordered both. He did everything he needed to do and more, with high attention to detail despite being late for his next appointment. He saw that my battery was corroded so he cleaned it off and sprayed it with sealant with me even asking him to! One thing - he left my keys in the ignition the whole time he worked (about 1.5 hours) with music on and everything. My car battery almost died. Lucky it didn't, or my review might not be so great! My car sputtered for a bit when I started my car later that day - it almost wouldn't start. All in all, due to the convenience and high level of quality, I'd definitely use this service again! Lastly, keep in mind that these mechanics are very on-the-go and probably don't get a chance to eat or drink. Offer them water and/or snacks! A happy mechanic = a happy car.
