Ignition coil replacement

When and Why should replace ignition coils?

The ignition coil on car is supposed to last around 100,000 miles or more. You will have reduced gas mileage when coil begins to go bad and becomes less able to transfer power. Your car requires more fuel to run, this means you will spend more money on gas than normal.


A sputtering or jerking motion of the car is a sign of engine misfiring. The causes of misfiring could be faulty spark plugs or wires, bad fuel injector. Even transmission or mechanical problems and an imbalance in the air/fuel ratio could be reasons for misfires. Also you can check engine misfire codes to help you finding the causes.

As car is idling or low-speed, this may feel like engine shaking or a random, but repeated loss of power because coils send irregular electrical currents to the spark plug. If your vehicle has become difficult to start, replacing the ignition coil may be a solution to your problem.
