Can you drive with bad ignition coils?
It is possible to drive with a faulty Coil On Plug (COP), but not advisable. Driving with a faulty waste spark ignition system won’t be possible. Driving with a faulty coil pack can damage other components of the engine. You’ll also learn how to diagnose and replace your faulty coil.
Can a bad ignition coil cause an engine to stop?
Some ignition systems will use one coil to provide the spark for all of the cylinders, however most newer designs use an individual coil for each cylinder. As the ignition coil is the component responsible for generating the engine spark, any problems with it can quickly lead to engine performance issues.
Is it possible to drive with a faulty coil pack?
It is possible to drive with a faulty Coil On Plug (COP), but not advisable. Driving with a faulty waste spark ignition system won’t be possible. Driving with a faulty coil pack can damage other components of the engine.
How can I tell if my ignition coil is good?
Start the engine. Pull out ignition coil 1. See the engine condition changes: If the engine becomes rough or vibrates, it likely means that ignition coil has a malfunction. If the engine condition remains constant and doesn’t change, it means that ignition coil is good.
Can a faulty coil pack cause an engine to misfire?
A failed coil is the most likely cause of the misfire but it’s not the only possible cause. Other common causes include – fouled or faulty spark plug, fuel injector, vacuum leak or a compression issue may also cause a misfire condition. There are a ton more reasons an engine misfires, you can check them out here – “Why is my car shaking”.
What happens if you have a bad ignition coil?
Faulty ignition coils can affect the timing of when the spark plugs ignite, which causes misfiring and bad timing. Backfiring of the engine is a symptom of a bad coil pack. A vehicle that is stalling will undergo abrupt stops and starts, making it incredibly difficult and frustrating to drive – and not to mention quite dangerous.

When to replace spark plugs and ignition coils?
In cases like this, to prevent future problems, your mechanic may recommend replacing all three rear ignition coils. Whenever one of the ignition coils goes bad, it’s also recommended replacing all spark plugs if they haven’t been replaced in a while. New spark plugs will help ignition coils last longer.
Where is the ignition coil on a car?
Each new type of ignition system has brought the ignition coil closer to the spark plug. A coil now sits directly on top of each spark plug for each cylinder. This works much better — here’s an example: Let’s say a V8 engine fires four of its spark plugs every time the crankshaft makes one full turn.
