5 Bad ignition coil symptoms
As we already know, every gasoline engine needs a spark to burn the air-fuel mixture compressed inside the combustion chamber to produce engine power. Without the spark, the air-fuel mixture will not burn completely and cannot provide optimal engine power.
The only component in the car engine responsible for producing high-voltage electricity before being converted by the spark plug into a spark is an ignition coil. Yes, the ignition coil has a vital role in providing high voltage electricity to keep the engine running normally and optimally.
When the ignition coil has a problem, the engine condition will also have problems until the car breaks down or stops running. Well, in the following article, we will inform about five bad ignition coil symptoms.
1. The engine power is reduced
The first bad ignition coil symptom that indicates the car's ignition coil starts to fail is reduced engine power. Although this cannot be used as a benchmark, bad ignition coil symptoms will cause a lack of engine power.
Incomplete combustion due to abnormal spark plug fire is one of the bad ignition coil symptoms. It will directly impact the resulting explosive power and the engine power.
2. The engine shakes when accelerating
In addition to reduced engine power, bad ignition coil symptoms can cause the engine to start abnormally, shake when gassed or at a certain rpm. Sometimes limping occurs only at low rpm, but it can also occur at high and middle rpm.
Bad ignition coil symptoms generally occur at medium rpm, when the engine speed ranges from 2000-3500 rpm. The engine will often feel shaking and vibrate when held at this rotation.
3. Decreased Fuel Economy.
When the ignition coil has started to fail, the next symptom of a bad ignition coil is decreased fuel economy. The engine becomes wasteful of fuel. It occurs due to reduced engine power, making the driver accelerate more in-depth into the gas pedal to obtain engine power that suits the driver's needs. As a result, much fuel that should explode and produce engine power is wasted. It means that the vehicles have decreased fuel economy.

4. The engine is hard to start
The next bad ignition coil symptom that indicates the car's ignition coil is going bad is the engine becomes difficult to start. A damaged ignition coil prevents the spark plug from igniting the compressed fuel mixture. As a result, there was no explosion in the engine combustion chamber, so the engine was hard to start.
5. The engine stalls
The last thing that is a symptom of a bad ignition coil is the engine suddenly stalls. The ignition coil is no longer able to withstand hot engine conditions with long operating times. There is a possibility that the engine can be restarted when the temperature has cooled down.
