4 Signs of a Faulty Ignition Coil: Visit Your Lexus Dealer Today
A faulty ignition coil can spell disaster for your Lexus. That’s why it’s important to know the signs of a bad coil and what to do when you experience them. This blog post will discuss the symptoms of a faulty spark coil and how to get it fixed at your Lexus dealer.
Misfiring Engine
Misfiring can happen when there’s a problem with the spark plugs or wires, but it can also occur when the ignition coil isn’t functioning correctly. The ignition coil produces high-voltage sparks that ignite the air-fuel mixture in the engine’s cylinders, so when the coil fails, it causes a misfire in one or more of the cylinders.
In addition, the most common cause of ignition coil failure is excessive heat. The insulation on the coil’s windings can degrade because of the high temperatures, eventually leading to a short circuit. Engine vibrations can also damage the ignition system, causing premature failure. If you notice that your engine is misfiring, it’s essential to have it checked out by a mechanic.
Hard Start
If your car is having trouble starting, this could also be a sign that the ignition coil needs to be replaced. When the coil is defective, it can cause the spark plugs to stop firing correctly, making it difficult for the engine to start. If you notice that your car is taking longer than usual to start up or is having difficulty starting in cold weather, the ignition system needs to be replaced.
Poor Fuel Economy
When your ignition system starts to fail, one of the first signs is usually a decrease in fuel economy. As the coil begins to break down, it becomes less efficient at creating the spark that ignites the mixture in the engine. As a result, the engine has to work harder to maintain the same power level, resulting in increased fuel consumption. Therefore, if you’ve noticed that you’re filling up your tank more often than usual or decreasing fuel economy, your sparking coil needs to be replaced.
Check Engine Light On
The Check Engine Light is one sign that your ignition system is failing. If it’s coming on more frequently or staying on longer than usual, it’s a good indication that something is wrong. The light can come on for several reasons, one of which is a problem with the ignition coil. If the light is on and you suspect your coil is to blame, take your car to a mechanic right away to have it checked out.
