SYMPTOMS OF A BAD IGNITION COIL & WHEN TO REPLACE IGNITION COILS

#1 Engine Misfires
A weak ignition coil will cause “No Spark” situation as it is unable to deliver enough power for spark plug.
When “No Spark” situation appears, you will hear the sounds like “coughing” or “sputtering” when you start the engine.
It is the very common sign to tell you something is wrong with the coils.

 

#2 Vehicle Doesn’t Start
When the situation is more serious, the engine will not be just “sputtering”, which means you can’t even start the engine.

This will happen especially for the vehicles that only have 1 single ignition coil.
If this single coil has problem, the ignition system crashes down as it is unable to deliver power to the spark plug.
Without spark plug, the engine is dead.

 

#3 Car Idling Rough or Engine Stuttering
The broken ignition coil will cause the engine misfire and you will experience the rougher ride while driving. 
You may also feel the power loss or engine vibrating.
Let’s say several reasons may cause the engine misfire, but the ignition coil can be the culprit most often.

#4 Fuel Performance Getting Poor
In my case, I have the habit to calculate every time I fill the gas to see how many miles per liter my vehicle can run.
If the ignition coil is dying, the calculate result will decrease and you will feel it.

 

#5 Check Engine Light On
As we always talk about, any components in our engine go wrong, the ECL will be on to remind you to have a check.
So, it’s time to visit your repair shop now!

 

OK guys, these are the Top-5 signs to show you the ignition coil is dying.

Before jump into my Bonus Tip, I want to spend some time to talk about:

WHAT'S IGNITION COILS FUNCTION

Engine start needs spark plug to fire and this requires very high electricity around 20,000 to 35,000 volts to initiate. 
Ignition coils are like transformers to convert voltage from 12 volts to this high voltage pulse to fire the spark plugs. 
The number of spark plug varies on car models and it's a trend that number is increasing in newer models depends on the cylinder numbers.
Coil-on-plug type is getting more and more common which means each spark plug has its partner ignition coil to collaborate with to start the engine.

And if you’re wondering how much will it cost to replace the ignition coils, you may refer to this article:

The answer is No.
