A flashing check engine light means there is a serious problem with your vehicle, most commonly an engine misfire. This occurs when one or more cylinders fail to ignite the fuel properly, causing unburned fuel to enter the exhaust system. This can rapidly raise the temperature of the catalytic converter, potentially causing severe damage or even a fire hazard if ignored

. Key points about a flashing check engine light:

• It signals an urgent issue that requires immediate attention, unlike a steady check engine light which usually indicates a less critical problem

• Common causes include ignition system faults (like bad spark plugs or ignition coils), fuel delivery problems, or internal engine issues leading to misfires

• Continuing to drive with a flashing light risks costly damage to the catalytic converter and other engine components

• Signs of engine misfire include shaking or vibrations, jerky acceleration, loss of power, strange engine noises, and the smell of gasoline

• The safest action is to pull over and have the vehicle inspected by a qualified mechanic as soon as possible to prevent further damage

In summary, a flashing check engine light is a critical warning that your engine is misfiring and immediate professional diagnosis and repair are necessary to avoid severe and expensive damage
