Signs of a Bad Ignition Coil

One of the most important components in an automobile’s engine is the ignition system. The ignition system is used to create the spark that ignites the mixture of fuel and air in the cylinder of an engine.An ignition coil is a component in an automobile’s ignition system, which transforms the 12 volts generated by the battery to up to 20 to 30 thousand volts. Spark plugs are then sparked by this high voltage. A bad ignition coil can therefore cause your automobile to run poorly.

Some of the signs of a bad ignition coil are:

Vehicle Backfiring

Backfiring is one of the early signs of an ignition coil that is failing. It occurs when a mixture of air and fuel ignite in the vehicles exhaust system. Left unattended, backfiring can easily damage the car’s exhaust system. It is advisable to check your ignition coil immediately you detect that your vehicle is backfiring to avoid further complications.

Problems When Starting Your Vehicle

Another sure sign that your ignition coil is faulty is when you have problems starting the car when it is cold. Malfunctioning ignition coil symptoms generally prevent spark plugs from receiving adequate charge. When you experience starting problems, it is advisable to check the high tension cables to ensure there is a spark emanating from each cable to the spark plug it corresponds to.

Excessive Fuel Consumption

When you notice that your vehicle is consuming more fuel than it usually does then there could be a problem with your ignition coils. When your ignition coils are faulty, the ignition system does not supply enough power. Automobiles usually consume more fuel to compensate for the reduced power supply from the ignition system. When you notice that your vehicle s consuming more fuel than necessary you should get your ignition coils checked.

Misfiring Of Your Engine

This is one of the most common engine ignition coil symptoms faced by motorists. Engine misfiring is caused by incomplete combustion of fuel within the cylinder. The vehicle also tends to vibrate when idle. It often causes a sharp jerking action from the engine. It can be caused by several factors among them, coil ignition failure.

Engine Stalling

If your engine completely shuts down after bringing your vehicle to a stop then you may have a defective ignition coil. This is due to the fact that faulty ignition coils produce sparks that are irregular leading to engine stalling. This is among the most annoying symptoms of a bad ignition coil so it is best to have it checked once detected. You do not want to be stranded in the middle of nowhere at night just because you neglected a faulty ignition coil.

Faulty Coil

If your spark plug gap is increasing as a result of normal erosion, it may require extra voltage for a spark to be created in the chamber. This requires increased flow of current through the primary circuit. This increase in current can cause the primary transistor to get overloaded. It is very important to ensure that you keep all components in good working condition.
