Our mobile mechanic in Salt Lake City can come to you to perform this service, so you don't have to take your car into the shop.

What are Ignition Coils and Spark Plugs?

Ignition coils provide the spark that ignites the air/fuel mixture in the cylinders of the engine. Over time, ignition coils can wear out or become damaged, causing them to lose their ability to generate a strong spark.

Spark plugs ignite the fuel in the cylinders of the engine. Over time, spark plugs can become fouled or damaged, causing them to lose their ability to ignite the fuel properly.

How Does a Vehicle's Ignition System Work?

In order for a vehicle's engine to run, it needs three things: air, fuel, and spark. The job of the ignition system is to provide that all-important spark.

The ignition system consists of four main components: the spark plugs, the ignition coil or coils, the distributor, and the crankshaft position sensor.

The ignition system works like this:

1. The crankshaft position sensor sends a signal to the ignition control module telling it when the engine is in the correct position for ignition.

2. The ignition control module activates the ignition coil or coils, which produces a high-voltage spark at the spark plug.

3. The distributor routes the spark to the correct cylinder at the correct time.

4. The spark plugs ignite the air/fuel mixture in the cylinders, starting the engine.

When Should You Replace Your Spark Plugs?

Most mechanics recommend replacing spark plugs every 30,000 miles or so. However, some newer vehicles can go up to 100,000 miles before needing new spark plugs.

If your vehicle is starting to experience any of the following symptoms, it's a good idea to have the spark plugs checked:

    1. Reduced fuel economy

    2. Engine misfires

    3. Rough idling

    4. Slow acceleration

    5. Decreased power

How Do Mechanics Replace Spark Plugs?

Replacing spark plugs is a relatively simple task that most mechanics can do in about an hour.

To replace spark plugs, mechanics will:

    1. Remove the old spark plugs using a spark plug socket and ratchet.

    2. Inspect the spark plugs for any damage or wear.

    3. Gap the new spark plugs to the correct setting.

    4. Install the new spark plugs, using the spark plug socket and ratchet.

    5. Reconnect the spark plug wires.

    6. Start the engine and check for any leaks.
