Jaguars are elegant, luxurious, and comfortable vehicles; although, that doesn’t mean they’ve sacrificed performance for comfort—quite the opposite in fact. Jaguars are highly functioning cars that produce plenty of power for the average driver and wow enthusiasts all over the world. However, just like any other car on the road, Jaguars require ongoing care and routine maintenance in order to perform well. Even with the most efficient, adequate care, problems can still arise at no fault of the owner or driver. Jaguars have common issues amongst them, and with the help of a trained Jaguar specialist you can cut the snake off at its head before things get out of hand.

One such issue in several different Jaguar models is ignition coil misfiring. When an ignition coil misfires, it can cause serious engine problems and performance issues. Therefore it’s important to have a little background information about ignition coils and what they do for your Jaguar’s performance. In this blog we’ll talk about the basic function of ignition coils, the reasons behind ignition coil misfire, and the signs that might indicate ignition coil issues.

What Does an Ignition Coil Do?

In basic terms, the ignition coil is responsible for converting and bridging the energy exerted by the spark plugs, helping the engine to ignite or combust when the energy comes into contact with the air/fuel combination. As you can tell, the ignition coil is essential for your Jaguar’s functioning. With a history of ignition coil issues, Jaguar vehicles must be carefully and routinely looked after and assessed.

Common Causes of Ignition Coil Misfiring

There are a number of reasons why your Jaguar’s ignition coils could begin failing or misfiring. One common reason for ignition coil problems is bad or failing spark plugs. While it’s common for the spark plugs themselves to be malfunctioning, it’s even more common for something to go wrong with the spark plug ignition cables. In Jaguars, these cables tend to over function or malfunction, which creates too high of a temperature for the wiring to withstand, ultimately causing ignition coil failure or misfire. Keeping your eye out for any troubling symptoms related to your engine’s function would help prevent ignition coils from misfiring or failing.

Concerning Symptoms to Look Out For

The symptoms related to ignition coil misfiring are certainly alarming for the average driver, and should be addressed with urgency. These are the most common signs that Jaguar drivers tend to experience:

Check-Engine Light Illuminated: Your car is designed to alert you of any slight changes in engine performance, and will certainly detect ignition coil problems. If the check engine light comes on, it’s best to bring it to a Jaguar specialist for diagnosis.

Engine Misfires: This is one of the more severe consequences of ignition coil problems that affect drivers the most. This is not a symptom you can or should ignore.

Engine Stalling and Rough Idling: Along with misfiring, stalling is another concerning symptom that your Jaguar should never experience under proper conditions. Additionally, if your Jaguar is idling roughly, the problem could be related to ignition coil malfunction.

Lowered Power Upon Acceleration: When ignition coils can’t deliver the necessary power to your Jaguar’s engine, acceleration can be hindered significantly. You’ll notice a change or hesitation in your Jaguar’s behavior when attempting to accelerate and gain more momentum/power.

Ignition Failure: If you encounter ignition failure, you won’t be able to start your car. This usually happens at the most inconvenient or urgent times, when we least expect it. Therefore, it’s best to act preventively when it comes to ignition coil functioning.
