How Do I Know If I Need To Replace The Ignition Coil?

　　It is important to know when to replace the ignition coil so that you can keep the engine running smoothly.

　　The most common symptom of ignition coil failure is engine misfire, that is, one or more cylinders in the engine cannot be properly ignited due to lack of air, fuel, or lack of spark in this case. Misfires usually manifest as gross idleness or lack of power.

　　In some cases, a malfunctioning ignition coil can even prevent the vehicle from starting. However, your vehicle may fail to start due to a variety of other reasons, including a dead battery or a malfunctioning starter. A technician’s diagnostic test can determine whether your ignition coil is the cause of poor engine operation.

　　If the ignition coil needs to be replaced, your check engine light may come on. However, this light may be on for many other reasons, and the mechanic can check your vehicle to determine the problem.

　　If your vehicle consumes more fuel than usual, this may also indicate that it is time to replace the ignition coil. This is because if the spark plug does not get enough power due to a malfunction of the ignition coil, your vehicle will compensate for the drop in power by increasing fuel consumption.

　　Flashback can also be a sign of a problem with the ignition coil. The counterproductive feature is the loud impact. You may also see black smoke coming out of the exhaust pipe. This is abnormal and may indicate that your ignition coil is malfunctioning.

　　Pay attention to these signs of ignition coil failure. Knowing these signs will make it easier for you to determine when to replace the coil assembly or ignition coil.

　　What happens if I don’t replace the ignition coil?

　　Knowing when to replace the ignition coil is the first step. The second step is actually to contact the mechanic to replace it.

　　Vehicles with one or more faulty ignition coils will lack power and perform poorly, or sometimes fail to operate at all.

　　In addition, a stalled engine running for a long time may damage the catalytic converter and the oxygen sensor due to the unconsumed fuel entering the exhaust system.

　　Most importantly, if you think you need to replace the ignition coil, you should not drive the vehicle. If you continue to drive a vehicle with a malfunctioning ignition coil, you may severely damage the engine.
