Suppose you’re on a road trip, riding through the wind like a stallion; the surrounding is breathtaking. And then your spark plugs get broken in the middle of nowhere.
So now the question is, how far can you drive with a blown-out spark plug? Most importantly, is it even safe to do that?
Well, you don’t know when you’ll become a victim of circumstances like that. And so, to be aware, keep scrolling to know everything about dealing with this issue successfully!
Can I Drive with a Blown-Out Spark Plug?
If the spark plug is blown out entirely, your vehicle won’t start. Yes, that’s it!
When the spark plugs get destroyed, there’ll be a burst of electricity in the coil. As a result, the engine won’t have enough torque to push the pistons over. Hence, it may turn over if you try to start your vehicle, but you won’t be able to drive it.
However, when there’s still some life left on the plugs, meaning the spark plugs are badly damaged but not blown yet, you might be able to drive your car for a few miles.
So yes, there’ll be enough time for you to reach help as you can’t fix it in the middle of the road. But the problem is while driving a vehicle with a blown-out spark plug, you’ll face tons of performance issues.
For instance, the fuel consumption will be crazy high, and there’ll be some acceleration troubles as well. And if you keep driving in that condition, the engine will get damaged pretty badly, and you don’t want that.
So, when your car’s going through spark plug issues, it would be better if you don’t drive the car for too long. Once you can get help, park your car right there, call a mechanic, or fix it by yourself, whichever you prefer.
What Are the Symptoms of a Damaged Spark Plug
To ensure a better driving experience, you should know the blown spark plug symptoms. This way, you can foresee the upcoming danger and take steps accordingly.
Engine Misfiring
One of the most common symptoms of damaged spark plugs is a frequently misfiring engine. When the engine is misfiring, you’ll be having a problem with the acceleration.
As a result, you won’t be able to run at full speed, and there’ll be no smoothness in the car’s performance whatsoever. However, engine misfiring can happen due to many reasons.
This issue can be caused by a badly damaged ignition coil plug cap or if you’re using cheap fuel. But when it’s happening continuously, you should definitely inspect the spark plugs before doing anything else.
If there’s any damage, take steps accordingly to ensure the safest driving experience.
Having Issues While Starting the Vehicle
A blown-out or worn-out spark plug will never allow your vehicle to start. Therefore, whenever you feel any hitches while starting your car, you can take a look at the spark plug to make sure if they need any repair or not.
Mostly battery problems or an empty gas tank stop the car from starting smoothly. But even after reviewing those problems, the vehicle is failing to start.
It means that the engine isn’t getting the spark needed for starting the combustions. Thus, check out your spark plugs whenever you’re experiencing this particular complication.
Excessive Fuel Consumption
Another common symptom indicated your vehicle might be having spark plug problems. When the plugs are worn out, there’ll be massive energy consumption. So, if buying gasoline for your car and clear out your bank account, it’s time to inspect the spark plug.
If your car runs with faulty spark plugs, the fuel won’t be properly burned in the combustion chamber. Consequently, the engine will suffer from frequent engine misfires, and your fuel economy will take a serious hit.
So, if you think you’re buying more fuel than usual, but you’re not going on any extravagant car rides, examine the spark plugs to solve the case.
Engine Knocking
Are you hearing any knocking sound from your car’s engine while turning up the speed? If so, your vehicle may have a damaged spark plug.
When the spark plug fails to detonate accurately and ignite all the gas, the fuel, and vapor will fire. If it occurs, you’ll hear a knocking sound from the engine. But this degree of spark plug damage can be salvaged.
