How far can I drive with check engine light blinking?

Depending on the issue that triggered the Check Engine light, you may be able to continue driving indefinitely or only for a couple of days. Covering a distance between 50 and 100 miles gives the engine computer time to recalibrate certain sensors, which may solve the problem.

Is it safe to drive a car with the check engine light flashing?

A flashing light indicates a more serious problem like an overheating engine or engine misfires, which can cause irreversible damage. If the check engine light is flashing, you should stop, turn off the car, and call for assistance.

Should I be worried if engine light is blinking?

A flashing check engine light indicates a much more serious issue. Most often it means that the engine is misfiring and unburned fuel is getting into the exhaust system. This raises the temperature of the catalytic converter and can cause critical damage.

What are 3 common possible causes of a misfire?

The most common causes of misfires are worn, improperly installed, and mishandled spark plugs, malfunctioning ignition coils, carbon tracking, faulty spark plug wires and vacuum leaks.

Can a misfire fix itself?

While your engine can regain normal RPMs after a misfire, it's not likely that the problem will fix itself. If your engine is misfiring, it must be taken to a mechanic to diagnose and repair it.

Why did my check engine light start blinking?

A flickering engine light will usually mean there is a problem within one or more of these areas: Fuel injector. Oxygen sensor, airflow sensor, or other parts of the computing system. Ignition coil, spark plugs or spark plug wires.

Why is my check engine light flashing then stops?

A flashing check engine light usually refers to cylinder misfiring. Misfiring should be investigated and resolved promptly - that's why the light flashes versus simply staying steady - because misfiring can damage the catalytic converter which can result in additional costly repairs.

Why would a check engine light flash?

While the check engine light can definitely be indicative of serious problems, the most common cause of the flashing is usually an engine misfire. There are many reasons why an engine misfire might be occurring. To run smoothly, an engine must be receiving the correct amount of power from the cylinders in your vehicle.

Can a misfire ruin an engine?

An engine misfire can be caused by bad spark plugs or imbalanced air/fuel mixture. Driving with a misfire isn't safe and can damage your engine.

Misfires can happen when a vehicle is under load while accelerating. This causes slow or sluggish acceleration and your vehicle may have trouble getting up to speed. You might feel a jerking motion when pressing down on the throttle. The most common cause of an engine misfire when accelerating is worn-out spark plugs.

Can low oil cause misfire?

Low engine oil can cause a misfire, and it is very likely that the cause of the misfire was indeed the low oil pressure in your vehicle. There are three common ways low oil can cause a misfire: Your oil filter is damaged, reducing oil flow, causing improper valve timing, and resulting in a misfire.

What sensors can cause misfire?

If an oxygen sensor or mass airflow sensor is failing, it could give incorrect data to your engine's computer, causing the misfire. When a vacuum line is broken, it can cause a fuel-injected motor to misfire.

Will changing spark plugs fix a misfire?

Dirty or Old Spark Plugs

If your engine is misfiring, you may be able to fix the problem easily by replacing your spark plugs. Spark plugs are relatively easy to remove from engines and inspect for damage, and at less than $25 a piece, they are relatively cheap to replace, too.

How do you stop engine misfire?

Inspect the spark plugs for signs of damage.

Use a spark plug socket to remove the plug so you can get a good look at it. The damage you see will help you determine the cause of the misfire. If the spark plug is just old, replacing it may solve the problem. Make sure to replace and properly gap new spark plugs.

How long does it take a misfire to damage the catalytic converter?

Any raw fuel in the catalytic converters quickly overheats them and leads to their destruction. If misfires occur severely then damage occurs quickly. If misfires are subtle, then damage may not occur for a year or two.

What does a engine misfire sound like?

So what does a misfire sound like? During a misfire, the engine will make a sudden sound that can be described as popping, sneezing, or backfiring. Backfiring occurs when unburned fuel exits the cylinder on the exhaust stroke and is then ignited farther in the system by the spark of the next cylinder.

Can I drive with a misfire?

While you can still drive a car with a misfire, it's not a good idea. A misfire could be a sign of several different engine issues. If you continue to drive without resolving the issue that caused the misfire in the first place, it could potentially cause more extensive damage to your engine over time.

How long can you drive with a misfiring spark plug?

In theory, you could drive thousands of miles with a cylinder that misfires. The other cylinders in the engine will continue to operate, so even though you may shake and stall along the wall (and not get much in the way of speed or acceleration), the car will still run.

Can bad gas cause a misfire code?

#2 – Problems with the Fuel

A tank of “bad gas” (incorrect octane or old gasoline) can cause a misfire. Weak or dirty fuel injectors can restrict the flow of fuel into the cylinder leading to the wrong air/fuel ratio.
