How to Determine When to Replace Ignition Coils?
1 Answers
Check if the cold start is smooth, whether there is any particularly noticeable jerking sensation, and if the ignition is normal. Keep the car idling; if the engine runs smoothly, it indicates that the spark plugs are functioning properly. If the engine exhibits intermittent or continuous shaking, it indicates a problem with one of the spark plugs, and the spark plug needs to be replaced.
