What are spark plugs all about?

The spark plugs are an important part of the ignition system. When you turn the ignition key (car's key) on, it causes the ignition coil to generate the spark which ignites the air-fuel mixture in the engine cylinders to start the engine. The number of spark plugs in the car is the same as the number of cylinders, although some vehicle manufacturers will use two spark plugs per cylinder.

Over time, the spark plugs wear out and require replacement. When the spark plugs wear out, it is harder for it the air-fuel mixture to ignite, resulting in engine misfires. If one of the spark plugs has failed, the car will still start and run, but it will run poorly. On some vehicles, spark plug replacement may be labor intensive and involve removal of the intake plenum.

While replacing spark plugs remember

  • When the spark plugs are replaced, it is a good idea to inspect the ignition cables as well.
  • Spark plugs come in numerous ratings, and the correct rating for your vehicle should always be used.

Steps for replacing spark plugs

  • Scan the car for codes.
  • Clean all surface areas around the spark plugs.
  • Remove spark plugs.
  • Inspect threads in engine head (where plugs are installed).
  • Perform compression test if needed.
  • Inspect ignition wires.
  • Apply anti-seize to the threads of the spark plugs.
  • Install new spark plugs.
  • If needed replace any gaskets removed.

When to replace spark plugs

During routine maintenance and checkups, your ignition system should always be inspected. Any time that a component of the ignition system is replaced, it’s a good idea to consider replacing the spark plugs as well. If you don’t preemptively change your spark plugs your engine will let you know by misfiring or running poorly, so schedule an inspection as soon as you notice that your engine is not performing properly.

What common symptoms indicate you may need to replace the Spark Plugs?

  • Check Engine light is on.
  • Engine misfires.
  • Poor fuel economy.
  • Vibration coming from the engine.

How important is it to replace the spark plugs?

Spark plugs are responsible for igniting the fuel that your engine uses to run. When you turn your key, a small voltage of power is sent to the ignition coil, where it is transformed into high voltage currency. This high voltage currency is sent through the ignition cables to the spark plugs. The spark plugs use the power to create a spark, which ignites the fuel, and allows the engine to function.

When the spark plugs malfunction, this spark won’t be created, and the fuel will not be ignited as it should. Your vehicle has many spark plugs, so depending on how many fail, your engine may either run poorly, or not run at all. Continuing to drive a vehicle with malfunctioning spark plugs can also cause damage to the catalytic converter.

Regarding my Toyota 2001 XL. I required several automotive services to be done. The car needed the following: Timing Belt, Water Pump , Power Steering Belt & Serpentine Belt Replacement: Spark Plugs & Valve Cover Gasket replacement; 02 Oxygen Sensor Replacement ( Code p1135) PVC Valve Replacement: Drivers side door handle Replacement: Throttle Body Maintenance: This was my first time using Auto Mechanic online for Automotive Service: My appointment was set-up for 02/19/2018 Presidents day. The technician to performed the above mentioned automotive service was Mr. Jamahl Walker. On my appointment date Mr. Jamahl Walker showed up as promised at 08;55 am ahead of the scheduled appointment time. From the moment of introducing himself, he was extremely courteous and respectful. He provided an overview of his automotive training and stated that his father was a master mechanic and worked under him for several years. Indeed! it was a pleasure watching how Jamahl performed and install the various parts on my car. He could explain how the various parts worked in conjunction with each other. At the end of the day I highly recommend Mr. Jamahl Walker and his workmanship. On a scale of 1 thru 5, with 1 being the lowest and 5 highest I rate Mr. Jamahl Walker a 5+++++.
