There are several possible symptoms of an ignition coil problem. 

The ignition coil on your hand may be faulty if your car experiences any of the following problems:

01)The engine is on fire

02)The idle speed is unstable

03) Decreased power, especially acceleration

04)Poor fuel economy

05)Difficulty starting the engine

06)Check whether the engine light is on

07)Exhaust tempering

08)Increased hydrocarbon emissions

09)The smell of gas from the exhaust port

10)Fuel leakage

What is the ignition coil?

Ignition coils, sometimes called spark coils, help start a car engine. It is an important part of the ignition system.

The voltage of a car battery is very low (12 volts), but thousands of volts are needed to start the spark plug ignition. The ignition coil is basically a small transformer that converts the 12 volts of a car battery into the required thousands of volts. Without the energy provided by the ignition coil, the spark plug cannot produce the spark needed to burn. Without burning, your car won't start at all!

Most engines have at least four ignition coils, sometimes combined in a single coil group. If a car has a problem with its ignition coil, it could affect its performance.

That's why it's important to be alert for the symptoms of ignition coil failure, which we'll cover in more detail now:

01)Engine starting difficulty

Difficulty starting a car engine can indicate a problem with the ignition coil.

02)Engine fire or stall

If your engine catches fire or stalls while idling or suddenly stops or accelerates, there may be a problem with the ignition coil.

03)Poor fuel economy

If you notice that your car gets less mileage than usual with a full tank of gas, it may mean you have a problem with the ignition coil.

04)Check engine light

The check engine light is designed to tell you that there is a problem with the engine. If you drive with a problem in the ignition coil, your check engine light will notice and light up.

How do I test the ignition coil

Testing the ignition coil can be dangerous if done incorrectly. If you don't know how to safely test the ignition coil, you should ask our 1D company for help.

▶For most other types of ignition coil tests, you will have to take a look. The location of the ignition coil varies from vehicle to vehicle, so check your vehicle's owner's manual or use a search engine to find the location of your car's ignition coil. Again, take proper precautions to ensure that you do not get electrocuted.


▶Once you find the ignition coil, you can look for any obvious signs of damage. The easiest part is to check the ignition coil wiring. If any wires are damaged or deteriorated, this could be the source of the ignition coil problem. You should also look at the coil harness and connectors for faults, especially bent terminal pins and loose connections. If you still can't find the problem, remove each ignition coil from the engine and carefully inspect it for signs of damage. Fluids can damage the ignition coil, so keep an eye out for signs of moisture.

▶After starting the engine, you should look for blue sparks along the spark plug gap. If you can see a blue spark, your ignition coil is working properly. If you do not see a blue spark or see an orange spark, you have a problem with your ignition coil. When finished, put the parts back in place.
