Hopefully, one of them will solve your problem. While it may be hard to imagine the cause of this problem, the truth is that your car could be having a few different problems at the same time.

A misfiring engine will result in a faulty catalytic converter and an errant check engine light. To find out which one is causing your car to stop, read on.

Symptoms and Causes of the Chevy Check Engine Light Flashing Then Stops


In some cases, the Chevrolet check engine light will turn on after filling with gas. You might think that the cap is loose or on the roof, but this is not the case.

The cap is simply in the wrong place. The cause of your car’s check engine light may be something more serious. In this case, you will need to visit a mechanic. However, if you still see the light blinking, there is a much more serious issue at hand.

Your check engine light is coming on because your vehicle’s ECU has detected a problem. Each error is logged into the ECU with a unique “P” code.

A diagnostic reader will read these codes to identify which component is faulty. In most cases, the ECU is easy to replace, but if you are not comfortable doing this, you can pay a mechanic to check it.

A Chevrolet check engine light may flash then stop, but there are several possible causes. The problem is usually related to a malfunctioning electronic control module (ECU), or the engine’s computer.

A computerized analyzer can diagnose the problem by reading the codes. If you can’t read the codes yourself, you can purchase a code reader at your local auto parts store. If it is still unclear, contact a professional who has experience in this area.

If you are experiencing these symptoms, you may be dealing with a misfire. In a misfired engine, the fuel mixture isn’t optimal, and a faulty ignition coil can cause cylinders to misfire.

Misfired cylinders can also damage the catalytic converter. This is an expensive repair. So, it is best to get it checked by a mechanic as soon as possible.


The check engine light on a Chevy will start to flash. While the light may appear to be a temporary problem, it can actually be an indicator of a more serious problem.

This type of malfunction requires immediate attention. If you notice that your check engine light is flashing, you should stop driving and visit a mechanic as soon as possible. If you don’t know what to do, follow the tips below to troubleshoot this issue.

When the “check engine” light comes on, it should stop after 6 seconds. If it stays on, the problem could be a small mechanical problem or wiring issue.

If you can safely stop the car, this is a sign of a larger fault. To fix the problem, consult a trusted mechanic. Here are some other possible causes for the check engine light on Chevy. The faulty wire is a common cause.

Another cause of the check engine light on a Chevy is a malfunctioning computer. The computer in the car monitors the engine’s performance and emissions.

When something goes wrong, the computer will trigger this light. The best way to solve this problem is to visit a mechanic.

An auto parts store or a mechanic can download codes for your car and diagnose the problem. But before you take your car to a mechanic, make sure to read the manual carefully to understand the codes displayed.

Other common causes of Chevrolet check engine light flashing then stopping include a misfiring engine. This condition could cause major damages to your engine.

It would not be safe to drive the car in such a state. However, you shouldn’t ignore it unless you know what is causing the problem.

By ignoring the flashing light, you risk severe engine damage and expensive repairs. So, be sure to visit your mechanic as soon as you notice this issue!

Another reason for your car’s check engine light to start flashing is an idle air control valve. If this is malfunctioning, the amount of air entering the engine will be reduced.

This can cause the engine to misfire or stall. To find out the cause of this problem, you can run an engine diagnostic. It will give you an error code P0505. Once you identify this, it will be easy to troubleshoot the problem and fix it.

#Symptoms of a faulty sensor or ignition coil

A faulty ignition coil is one of the most common reasons your car won’t start. You may notice that the engine starts but struggles to stay warm.

A faulty ignition coil may also cause your car to hesitate when trying to accelerate. To diagnose the issue, check your owners manual.

If you do not see any of the above symptoms, your car’s ignition coil could be faulty. In any case, you should visit a mechanic right away.

The ignition coil is an electronic engine management component that acts like an induction coil, converting 12 volts from the battery into the spark needed to ignite the air-fuel mixture.

Older cars and vehicles used a single ignition coil for all cylinders. However, modern cars and trucks use individual coils for each cylinder.

Symptoms of a faulty ignition coil include misfiring, decreased power, and poor gas mileage. In severe cases, your car’s engine could even stall, causing an unpleasant ride.

You can check your vehicle’s ignition coil by using a diagnostic scanner. These tools can also be used to determine if you’ve spotted any bite marks or damage to your vehicle’s engine compartment.

The malfunctioning coil can cause error codes P0350 to P0362. If the code comes back at a later date, the ignition coil can have a negative impact on other parts of the car, including the catalytic converter.

If your car doesn’t start, the check engine light will likely illuminate on the dashboard. The ignition coil is a critical component of your car’s ignition system.

Without it, your car won’t run at all. If you notice any of these symptoms, you’re probably experiencing a faulty ignition coil.

And if you’re wondering whether your car’s ignition is working properly, you should immediately repair the issue before it gets worse.

A faulty ignition coil can also cause your engine to misfire, leading to an engine misfire. Your check engine light will usually illuminate, so a quick check of your vehicle’s diagnostic codes will tell you whether the problem is related to the ignition coil or another component.

In the event that you do notice engine misfiring, you should visit a mechanic or use an OBD-II scanner to check your car for any possible problems.

#Cost to repair

What causes a Chevy check engine light to flash and then stop? It’s a warning sign that the engine may be experiencing some problems.

However, if the Check Engine Light doesn’t illuminate, you might have to take your car to a professional to determine what’s wrong.

A Chevy technician can use a code reader to pinpoint the exact cause of the problem and plan the best course of action to fix it.

Symptoms of a malfunctioning engine can range from a loose gas cap to a faulty oxygen sensor. The cause of the malfunction is critical and will require immediate attention.

A flashing check engine light indicates a high-level problem that requires quick repair. If it flashes rapidly, however, the vehicle needs to be towed to a mechanic right away.

If the Chevrolet check engine light flashes on and off intermittently, this is not a serious problem. However, it should not be ignored because it could cause severe damage to the engine.

If the warning light flashes rapidly, the engine might be experiencing a serious problem and should not be driven at all. A faulty engine can cause a car to run improperly or even fail completely.

The most common reason for a Chevy check engine light to flash and stop is a bad oxygen sensor. The sensor monitors the level of oxygen in the exhaust and controls the proportion of fuel to air.

If the sensor is defective, the engine can misfire, causing expensive damages to other major components of the car. Depending on the cause, this type of problem can cost anywhere from a few dollars to hundreds of dollars to fix.

If you’re unsure of what might be the cause of your car’s check engine light, it’s best to consult with a professional mechanic before taking your car anywhere.

If your check engine light keeps flashing and stopping, your car may need to have its catalytic converter replaced. It helps to convert carbon monoxide into carbon dioxide, but when this part is damaged, it can affect emissions tests.

The catalytic converter will also decrease the efficiency of your car’s engine. It can also cause extra problems from overheating. All of these problems can affect your car’s performance and fuel economy.
