Will a new ignition coil improve performance?
A high performance ignition coil helps engine performance four important ways. First, the higher voltage allows for a larger spark plug gap, which results in a more robust initial flame kernal at the start of combustion. The result is a real-world engine torque increase.
What causes ignition coils to go bad?
The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance. This excessive voltage creates a high amount of heat which consequently melts the coil's wire insulation.
What can cause an ignition coil to fail?
Ignition coils are very rugged and reliable, but can fail for a variety of reasons. Heat and vibration can damage the coil's windings and insulation causing shorts or opens in the primary or secondary windings. But the number one killer of ignition coils is voltage overload caused by bad spark plugs or plug wires.
How often do ignition coils fail?
The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.
Can you replace an ignition coil?
Ignition coil replacement can be challenging on some vehicle's engines. The greatest obstacles you'll face is accessibility and sticking components such as the ignition coil insulator boots sticking to the spark plug and tearing apart during the removal process. Some ignition coils can be difficult to reach and require removal of the upper plenum/intake manifold. In these cases, a new plenum gasket will be needed. Check the Repair Guide for your specific vehicle and engine.
What causes a misfire in a cylinder?
Note the term “misfire”, not “failed coil”. Misfires can be caused by many reasons. Related ignition system parts such as a spark plug, or fuel system component such as a fuel injector, a vacuum leak, or even an internal mechanical engine problem creating low cylinder ...
What causes a miss fire?
Related ignition system parts such as a spark plug, or fuel system component such as a fuel injector, a vacuum leak, or even an internal mechanical engine problem creating low cylinder compression, are potential sources for miss-fire symptoms.
What does it mean when your CEL flashes?
If your vehicle's CEL was flashing, most likely there's a misfire code stored in the PCM (the car's computer brain). Use a code reader (or drop by your local AutoZone) to read the code. In most cases the code will identify the culprit cylinder with the misfire. Note the term “misfire”, not “failed coil”.
Do I Need To Replace Ignition Coils With Spark Plugs: The Basics
Before we answer the question “Do I need to replace ignition coils with spark plugs?” — let us first cover the basics to understand things better. First of all, what is an ignition coil? Ignition coils are electrical components on the engine.
Do I Need to Replace Ignition Coils With Spark Plugs: How often should ignition coils be replaced?
It's critical to understand when an ignition coil needs to be replaced in order to keep your engine operating properly. Normally, an ignition coil on a car should last for at least 100,000 miles. When the coil starts to wear out and loses its ability to transfer power, you'll notice a drop in gas mileage.
Do I Need to Replace Ignition Coils With Spark Plugs: What are signs of a bad engine coil?
Besides the things already mentioned, a defective ignition coil can also hinder a car from starting in some situations. Your vehicle could also not be starting for a variety of reasons, including a dead battery or a defective starter.
The Verdict: Do I Need to Replace Ignition Coils With Spark Plugs?
Ignition coils and spark plugs are inextricably linked. If one fails, the other will be unable to work correctly. So do I need to replace ignition coils with spark plugs? The answer is that it really depends. The most common component to replace in conjunction with the ignition coils is the spark plugs.
What is an automotive ignition coil?
