    Spark plugs are part of a small group of parts that make up the ignition system. In reality the ignition coil is held in 2 places: Purchasing inferior parts may lead to a repeated repair. That sounds much more reasonable. Replacing your spark plugs can be one of the easiest, or frustrating experiences you can have as a DIYer.

    Spark plugs are part of a small group of parts that make up the ignition system. To accomplish this task, the spark plug turns high voltage electricity from the ignition coil into a strong spark inside the engine. As we discussed, spark plugs are necessary for any gasoline engine to run. When they fail , the engine is in a constant state of attempting to ignite air and fuel, but cannot.

    The first sign will be the check engine light, which may appear solid or flashing. This can happen many times before the spark plug fails completely, or continuously until repaired. It is important to understand that the check engine light can mean many things, and scanning the vehicle with an appropriate scanning tool is necessary to identify why the check engine light is on.

    Upon scanning the vehicle, on-board diagnostic OBD trouble codes will be displayed, and the following codes can indicate spark plug failure: All of these codes indicate a misfire, and the driver would likely notice one or more of the following: Engine vibrations, Rough idling, Poor gas mileage, Excessive cranking time needed to start the engine, Power loss or surging.

    In extreme circumstances, the engine may stall, or fail to start. Driving with the presence of the mentioned symptoms sends unburned fuel from the engine into the exhaust at a higher rate, and causes undue stress on the catalytic converter, the engine's exhaust cleaner.

    Since the catalytic converter is not made to handle a large amount of unburned fuel, failure may occur, and necessitate costly repairs. Spark plugs have no moving parts, but they are exposed to extremely high temperatures, fire, gasoline, carbon, and high pressure.

    Even with this harsh environment, failure is most common after , miles of use under normal driving conditions, but is greatly shortened if the vehicle is used under harsh conditions. A vehicle with the mentioned symptoms must first be connected to a professional scan tool, which will allow the technician to understand why the engine may not be operating correctly. If the spark plugs are suspected, they are checked for proper connection with the spark ignition coil, or spark plug wire on older models.

    If contact is confirmed good, the spark plugs must be removed, and the spark plug gap must be checked. If the gap is too small because of corrosion, or too large because or deterioration, they will be replaced. If the spark plug is in good condition, a spark plug tester is used to indicate whether or not the spark plug produces spark. Replacement of spark plugs on newer vehicles requires the removal of the engine cover, ignition coil harness and ignition coils, and the finally the spark plugs.

    For most older vehicles only the spark plug wires and spark plugs are required. There are cases in which the spark plugs are not accessible without raising or leaning the engine. Once the spark plugs are removed, the gap on the new spark plug is set to specification, and installed into the head with an anti-seize compound and proper torque.

    Prior to reinstalling the spark plug wire, or ignition coil, dielectric grease is applied to the spark plug terminal to promote transfer of electricity. We recommend replacement of the spark plugs in accordance with the factory specified maintenance intervals. In most cases, this scheduled allows the spark plugs to be changed before they become faulty, which saves money on diagnostic fees.
