If your Jaguar has failed to start or is having a misfire then you need to act fast. The problem could be stemming from an ignition coil. Like every other vehicle, your Jaguar has different parts of the ignition system and they help to supply electrical energy to the spark plugs for ignition of the fuel-air blend in the engine. Nonetheless, these coils can degrade with time as a result of heat, corrosion, wrong connection of wires, and much more.
If an ignition coil fails, a number of things can go wrong, including the car not starting, running roughly, losing power and performance, and burning fuel inefficiently. Continue reading to know the common Jaguar ignition coil trouble symptoms and the procedure on how to replace them so as to revive the performance of your Jaguar.
Symptoms of Ignition Coil Issues That You Need to Be Wary Of
- Engine Misfires: The general sign of a faulty ignition coil is a misfire which is a symptom of a weak spark. If a coil is not producing sufficient voltage to the spark plug, then, the fuel in the engine does not ignite as it should and leads to misfires. This results in slow acceleration and rough running, and when the engine is working you may experience a jerky ride.
- Poor Fuel Economy: When the ignition coil is not working properly then the engine will burn more fuel as a result of the power output. It can reduce fuel economy significantly, which means more stops at the gas station will be needed.
- Check Engine Light: The engine warning light can light up on your Jaguar when the ignition coil is faulty. This light can mean a lot of things, but if you get other symptoms such as misfires or rough running, the coil is probably the culprit.
- Difficulty Starting: If one or more of the ignition coils have failed, your car may have a hard time starting, especially in the winter. This is because the engine isn’t receiving the correct spark to burn the fuel as it should.
- Vibrations or Shaking: Defective ignition coils can cause the engine to shake or vibrate while in idle or acceleration.
When you notice all of these signs, what should be the next line of action? Let’s find out!
What Should Be Done About Ignition Coil Problems
- Diagnostic Testing: The first thing to do when you suspect ignition coils are not working as they should is to take your Jaguar to a qualified mechanic for a diagnosis. This way, they can leverage the equipment and discover if the electrical systems are the problem, or it is the coils.
- Replace Faulty Coils: If your mechanic has diagnosed that one or many ignition coils have gone bad, then they will have to be replaced. It is sometimes advised that all the coils should be changed simultaneously if they are old to eliminate other problems in the future.
- Regular Maintenance: One of the best methods of avoiding issues around the ignition coils would be frequent maintenance of your Jaguar. Replacing your spark plugs as you are advised and maintaining the efficiency of your engine’s electrical parts will also go a long way in prolonging the life of your ignition coils.
- Avoid Driving Through Deep Water: In order not to harm your ignition coils, do not drive through very deep water or through waterlogged roads. Water can penetrate the engine bay and the coils will short out.
