No, you should not drive a car with a bad ignition.
What Can You Do With A Car With A Bad Engine?
If your car has a bad engine, you have a few options for what to do with it. One option is to sell the car to a junkyard. Junkyards will take care of the process of dismantling the car and selling the parts, so you don’t have to worry about it. You can either sell the car as is, or you can sell it as scrap.
Another option is to try and sell the car privately. This may be more difficult, as most people will be wary of buying a car with a bad engine. However, if you can find a buyer who is willing to take on the repairs, you may be able to sell the car for a higher price than you would get from a junkyard.
Finally, you could always try to fix the engine yourself. This is likely to be the most expensive and time-consuming option, but it may be worth it if you are attached to your car. If you have the skills and knowledge to repair the engine, you may be able to get it running again.
Is It Safe To Drive A Car With A Bad Engine?
It’s not safe to drive a car with a bad engine for a few reasons. First, a misfiring engine will eventually damage your engine. Second, if you lose power while driving on a busy road, this is a safety hazard.
How Long Can You Drive A Car With A Blown Engine?
If your engine has blown, you will not be able to drive your car for very long. Some engines will stop operating altogether within one day, while others may last for a week or a few months if you use a temporary fix. However, it is not advisable to drive for an extended period of time with a blown engine, as this could cause further damage to your vehicle.
How Do You Know When Your Car Engine Is Blown?
There are a few telltale signs that your car engine is blown. One is if you notice a drastic decrease in power and performance. Another is if your engine starts making strange noises, such as knocking or ticking. Finally, if you see smoke coming from your engine, that is also a sign that something is wrong. If you notice any of these signs, it is important to take your car to a mechanic to have it checked out as soon as possible.
What Happens When Your Engine Blows While Driving?
If your engine blows while driving, the damage is usually so extensive that it affects most of the engine parts. This can include a cracked block, destroyed pistons, damaged intake and and exhaust valves, and more. In some cases, the engine may simply seize up and stop, while in others it may continue to run erratically, making weird metallic noises.
The cost of repairing a blown engine can be extremely expensive, often exceeding the value of the car itself. If your car has a blown engine, it is important to have it towed to a mechanic or dealership as soon as possible to avoid further damage.
How Long Can I Drive With A Bad Engine?
A car’s engine can continue to run without the serpentine belt, but it is not advisable to do so. Driving without this support can lead to the engine overheating, which can cause further damage. It is also dangerous because the vehicle could stall. If a car does overheat, the best course of action is to not panic and to turn off the engine. If a motor mount breaks, it is not wise to continue driving the car. It is also important to make sure that there is enough engine lubrication, coolant, and fuel before embarking on a long drive.
What Are The Signs Of A Blown Engine In A Car?
The most common sign of a blown engine is a head gasket leak. Other signs include a check engine light, decreased performance, and rough idle.

What is a Cylinder?
The cylinder is the part of the engine where combustion takes place. The combustion in the cylinder is what powers the vehicle. Depending on the type of vehicle, a normal engine may have as few as two cylinders to as many as 12 (the Bugatti Chiron has a 16 cylinder engine!).
A misfiring cylinder can cause a proportional loss of power. For example, if one cylinder misfires in a four-cylinder engine, the car will lose 25 percent of its power during each misfire.
Cylinder Misfire Symptoms
Some common cylinder misfire symptoms include:
- Power loss and strange vibrations
- Loss of engine spark
- Imbalanced air/fuel ratio
- Intermittent misfires
When you notice signs like power loss, strange vibrations, and shaking while idling, it could be a clear indication of a misfiring cylinder. This misfire leads to decreased engine performance and compromised fuel economy, as the remaining cylinders strain to compensate for the loss of power.
Additionally, a loss of engine spark due to worn or damaged components like spark plugs or ignition coils can contribute to cylinder misfires. As these parts degrade further, the frequency of misfires increases, affecting the engine’s overall performance.
Another factor contributing to cylinder misfires is an imbalance in the air/fuel mixture. A clogged or dirty fuel injector, along with issues like a sticking EGR valve, can disrupt the ratio of gasoline to air. Such misfires are often more noticeable at idle and can affect all cylinders rather than just one.
Intermittent misfires, occurring under specific conditions like cold weather or heavy loads, can also be challenging to diagnose. These issues may stem from various components like vacuum lines, intake manifold gaskets, timing belts, or even the valve train, requiring expert attention for proper repair.
Is it Safe to Drive with a Misfiring Cylinder?
No, it is not safe to drive with a misfiring cylinder. A misfiring cylinder poses significant risks and can lead to various safety concerns. Loss of power and acceleration compromises your ability to respond quickly to changing road conditions, while abnormal vibrations affect vehicle stability and handling.
Ignoring these symptoms can result in prolonged driving damage, like wear on critical engine components. Promptly addressing a misfiring cylinder is crucial to maintain safe driving conditions and prevent further vehicle damage.
Cylinder Misfire Engine Codes
A diagnostic trouble code (DTC) is a standardized system used in vehicles to identify and communicate issues detected by the OBD-II system. There are many trouble codes that are associated with a misfiring engine, ranging from P0300-P0312.
If any of the following codes are set in your vehicle, it means you have a misfiring cylinder and should contact a mechanic for a diagnostic:
- P0300: Random/Multiple Cylinder Misfire Detected
- P0301: Cylinder 1 Misfire Detected
- P0302: Cylinder 2 Misfire Detected
- P0303: Cylinder 3 Misfire Detected
- P0304: Cylinder 4 Misfire Detected
- P0305: Cylinder 5 Misfire Detected
- P0306: Cylinder 6 Misfire Detected
- P0307: Cylinder 7 Misfire Detected
- P0308: Cylinder 8 Misfire Detected
- P0309: Cylinder 9 Misfire Detected
- P0310: Cylinder 10 Misfire Detected
- P0311: Cylinder 11 Misfire Detected

Can You Drive with a Misfire? What Can Go Wrong in the Engine?
An engine misfire is a situation when one or more of the cylinders in the engine fails to produce the expected power ratio that drives the engine. It happens when the engine skips a part of its internal combustion cycle process. This unexpected change in performance may cause the vehicle to lose power leading to a stumble, or in serious situations, a complete stall.
Engine misfire highlights
- Level of importance:Medium
- Commonreasons:No spark, electrical problems, no fuel, low fuel pressure, injection issues, compression problems, internal engine damage
- DIY inspection:Possible but very complicated
- DIY repair:Impossible, in most cases
- Price for repair:$500 – $1,600
- Can you drive?Usually, yes
- Ways to fix:Locate the issue and let a professional mechanic fix it for you
Why the misfire?
The car ignition system is responsible for firing up the air-fuel mixture in the engine. The components involved in the firing process include the spark plugs, coils, fuel injectors, and ignition timings which must work in unison to produce the desired power. When any of these fail, the cylinders stop producing power leading to sudden engine idling, which is referred to as a misfire.
1) Imbalanced Air-Fuel mixture
As stated above, an imbalance in the air-fuel mixture causes an engine to misfire. The imbalance can be a result of the following factors or processes. If the air-fuel mixture in any of the cylinders becomes imbalanced the firing process is interrupted. This is because the air-to-fuel ratio in the cylinder must be per the engine’s requirement.
As such, the mixture fails to ignite, meaning at that particular compression cycle, there will be no power leaving the cylinder. The lack of a power cycle will mean less overall power for the engine, hence the stall or misfire.
The air-fuel mixture imbalance is brought by a malfunctioning fuel ejector or fuel pressure that is too low. The injector may have issues such as clogging, sticky EGR valve, or air leaks that prevent the normal ejection of fuel into the cylinder. This essentially reduces the amount of power emitted from the cylinder (or cylinders if several are affected), leading to a misfire.
2) Low Compression
If the air-fuel mixture escapes from the cylinder without ignition, compression is lost and that particular cylinder releases no power to the drive. The ignition of the air-fuel mixture in the cylinder builds up firepower compression that drives the cylinder up or down to release power. A low or no compression means the engine misfires and loses power momentarily (or continuously if the fault is repeated at every compression cycle).
Lost compression is caused by a leakage in the exhaust valve or if the cylinder head gasket has been blown. Such faults cause the air to escape before it is ignited in the cylinder.
3) Lost Engine spark
Some faults may prevent the electric spark from flowing through the spark plug gap. This can be a result of corroded ends, worn-out spark plugs, weak ignition coils, or damage in any of the electric circuit parts that supply ignition currents through the spark plug. A lack of an electric engine spark means the air-fuel mixture is not ignited which means the mixture leaves the cylinder without providing the expected firepower.
4) Mechanical Problems
There may be times when the engine misfires randomly without any consistency or pattern. This may happen when the vehicle is carrying a heavy load or when the engine is cold. Though it may be difficult to understand the actual cause of such misfires, it is an indicator of an underlying mechanical issue with the engine, more so concerning the valves, timing belts, or the intake manifold gaskets. Such problems require a thorough diagnosis of the vehicle to detect and rectify the problem.
Other mechanical issues that can cause a misfire include cracks in the combustion chambers, worn-out gaskets, or damaged valve trains.
Manifestation of Misfire
An engine misfire manifests itself when your car suddenly loses power and is slow to react when you step on the acceleration pedal, it shows a form of stuttering, a shaking steering wheel, or abnormal vibrations on idling. Apart from these sudden and obvious symptoms, you might also notice a significant drop in your car’s fuel economy, excessive exhaust smoke, or an increase in harmful emissions.
Sometimes, the car might come to a complete stall especially if all the cylinders misfire. If two cylinders in a four-cylinder engine misfire, it means the engine loses 50% of its normal power output at that particular instance. The loss means the engine cannot provide enough power to move the vehicle, making it slow down, start vibrating or stall completely.
You can also detect a misfire through changes in the engine sound. If the engine sounds abnormal, produces hissing, or extra loud noises, it could be a clue that the engine is misfiring (though not all noises are a result of misfiring).
Alternatively, your dashboard could alert you about a misfire that requires attention. Moreover, backfiring, sneezing engine sounds, malfunctioning ignition starts, or a check engine light on the dashboard may all be an indicator of a misfiring cylinder.
Is it okay to Drive with a misfire?
A misfiring engine can be driven for as long as the driver may deem it necessary. Depending on the depth of the problem, or the number of cylinders affected, the vehicle will drive along albeit with a little bit less power, stalling, or shaking/vibrations along the way. That said, it is not advisable to drive with a misfiring engine.
The most immediate threat to you while driving with a misfiring engine is a compromise on your safety. A misfiring engine may lack the power to accelerate while overtaking, may stall in the middle of the highway, or the vibrations may jeopardize your vehicle control.
Engine Damage
Misfires are likely to significantly damage your engine if allowed to hang longer than necessary. A simple misfire is not necessarily an engine problem and may be a result of a faulty coil, plug, or ignition current. However, when it lingers a little longer than necessary, it will lead to other more serious engine problems.
One of the most immediate effects is the destruction of the catalytic converter.
The catalytic converter filters all harmful by-products emitted by internal combustion and burn them up. Apart from this main function, the gadget improves your car’s efficiency, thus improving fuel economy. Once destroyed by a misfire, it means your engine output is reduced
The reason why a misfire should be treated immediately is to ensure the problem does not extend to other areas. Normally, misfires emanating from electrical faults are less harmful than those coming from mechanical issues. The latter would mean the engine is already at risk of failure aggravated by the misfire.
The immediate problem of driving on a misfiring cylinder is the probability of causing a strain on the other cylinders. Usually, the other cylinders will overwork to compensate for the lost power from the misfiring cylinder. The strain may cascade to the other cylinders causing a complete stall.
The un-burnt fuel in the cylinder damages the piston rings or the spark plug ends over time. This happens when the excess fuel cleans the oil lubrication from the pistons and cylinder walls, greatly increasing the tear and wear cycle of the piston rings. Damaged piston rings will lead to oil leaks into the combustion chambers, thus increasing oil consumption and reducing engine power output.
Elsewhere, the saturation of the combustion chamber by un-burnt fuel makes the engine run lean. Apart from lubrication, oil also acts as an engine coolant in the chamber. When it is cleaned by the excess un-burnt fuel, it means the engine will have excess heat when driving on a misfire. The pistons, valves, and cylinder heads will warp or crack due to this heat.
While modern cars move into limp mode upon detecting a misfire, it is advisable to fix an engine misfire immediately to limit the risks of serious engine damage that may arise from driving your car for long on an engine misfire. Have an experienced mechanic inspect your engine to rectify the misfire to avoid getting into a more expensive engine repair later.
Thus, it is not advisable to drive your car with a misfiring engine. Fix the problem first.
