One of the key components of a vehicle’s ignition system is the ignition coil. It is responsible for providing the electrical spark that ignites the fuel in the engine. When the ignition coil starts to fail, it can cause a range of problems that can affect the engine’s performance.
In this article, we will discuss the bad ignition coil symptoms and when to get an engine repair.
Bad Ignition Coil Symptoms
1. Check Engine Light
One of the most common symptoms of a bad ignition coil is the check engine light coming on. This can indicate a range of problems, including issues with the ignition coil. It is essential to have the vehicle’s computer scanned for error codes to determine the cause of the check engine light.
2. Misfires
Another common symptom of a bad ignition coil is engine misfires. Misfires can cause the engine to run rough or stall as well as damage to the catalytic converter. It occurs when the spark plug is not receiving the correct amount of voltage, which can be caused by a faulty ignition coil.
3. Poor Fuel Economy
A bad ignition coil can also cause the engine to use more fuel than usual. This is because the engine is not running efficiently and burning fuel correctly. If you notice a decrease in fuel economy, it could be a sign that the ignition coil is failing.
4. Hard Starting
If the engine is taking longer than usual to start, it could be a symptom of a bad ignition coil. This is because the spark plug is not receiving the correct amount of voltage to ignite the fuel. If the engine is hard to start, you should call a qualified mechanic to have it checked.
5. Backfiring
Backfiring occurs when the engine’s combustion process is interrupted, causing a small explosion in the exhaust system. This can be caused by a faulty ignition coil, which can cause the spark plug to misfire and ignite the fuel at the wrong time.
When to Get an Engine Repair for a Bad Ignition Coil
If you notice any of the symptoms listed above, it is essential to have the ignition coil checked by a qualified mechanic. Ignoring the issue can cause further damage to the engine and other components, resulting in costly repairs. Here are some signs that indicate it is time to get an engine repair:
1. Multiple Misfires
If you notice that the engine is misfiring on multiple cylinders, it is a clear indication that the ignition coil is becoming faulty. It is essential to have the ignition system checked by a qualified mechanic to determine the cause of the misfires.
2. Engine Stalling
If the engine stalls while driving, this might mean the ignition coil is failing and there is an issue with the spark plug that causes the engine to shut off. It is essential to have the vehicle checked by a qualified mechanic immediately to avoid further damage.
3. Electrical Issues
Another sign of an ignition coil failing is electrical issues, such as dimming headlights or a weak battery. This is because the ignition coil is responsible for providing the electrical spark that ignites the fuel. If the coil is faulty, it can cause electrical issues throughout the vehicle.
Conclusion
The ignition coil is a vital component in a vehicle’s ignition system. When it starts to fail, it can cause a range of problems that can affect the performance of the engine. If you notice any of the symptoms listed above, it is essential to have the ignition coil checked by a qualified mechanic. Ignoring the issue can cause further damage to the engine and other components, resulting in costly repairs.
