Preventive measures to prevent ignition coils from deteriorating
In addition to keeping your spark plugs clean, there are many things you can do to extend the life of your vehicle's ignition coils.
Signs of corrosion on the spark plugs can cause the ignition coils to fail, and you should also make sure they don't wear out from daily use.
Also, checking the condition of the ignition coil housing and checking for leaks can help you catch an ignition coil problem before it starts affecting your car's performance.
