Check Engine Light Flashing, Car Sputtering
What It Means
When the check engine light flashes and the car sputters, it means there is a serious problem with the engine. The flashing light indicates that the engine is misfiring, which can cause a loss of power, stalling, and even engine damage.
What to Do
If the check engine light is flashing and the car is sputtering, it is important to pull over to a safe location as soon as possible. Turn off the engine and call for roadside assistance. Do not continue driving the car, as this could cause further damage.
Causes
There are many possible causes of a flashing check engine light and sputtering car. Some of the most common include:
* **Spark plug problems:** Spark plugs provide the spark that ignites the air-fuel mixture in the engine. If the spark plugs are worn out or fouled, they can cause the engine to misfire.
* **Ignition coil problems:** The ignition coil provides the voltage that is needed to create the spark. If the ignition coil is faulty, it can cause the engine to misfire.
* **Fuel injector problems:** Fuel injectors spray the fuel into the engine. If the fuel injectors are clogged or faulty, they can cause the engine to misfire.
* **Air filter problems:** The air filter cleans the air that is drawn into the engine. If the air filter is clogged, it can restrict the flow of air to the engine, which can cause the engine to misfire.
* **Vacuum leaks:** Vacuum leaks can allow air to enter the engine without flowing through the mass air flow sensor. This can cause the engine to run lean, which can lead to misfiring.
Diagnosis
A mechanic will need to diagnose the cause of the flashing check engine light and sputtering car. The mechanic may perform a visual inspection of the engine, as well as use a diagnostic scan tool to read the error codes stored in the car’s computer.
Repair
Once the mechanic has diagnosed the cause of the problem, they will need to repair it. The repair may involve replacing the spark plugs, ignition coil, fuel injectors, air filter, or vacuum hoses.
Prevention
There are a few things you can do to help prevent a flashing check engine light and sputtering car:
* **Get regular maintenance:** Regular maintenance can help to keep your car running smoothly and prevent problems from developing.
* **Use high-quality parts:** When you need to replace parts on your car, be sure to use high-quality parts. This will help to ensure that the parts last longer and perform properly.
* **Drive conservatively:** Driving conservatively can help to reduce the wear and tear on your car’s engine. Avoid excessive acceleration and braking, and don’t drive at high speeds for extended periods of time.
Conclusion
If the check engine light is flashing and the car is sputtering, it is important to pull over to a safe location as soon as possible and call for roadside assistance. Do not continue driving the car, as this could cause further damage.
