⚠️ If It's Broken, Don't Fix It - Get Paid Cash for Your Vehicle ⚠️
In any vehicle equipped with a combustion system, air and fuel get mixed and ignited in a designated location referred to as the cylinder.
This combustion process must happen in the right place at the right time. So, if there's any disturbance impacting the combustion process, we'll deal with all sorts of troubles that could range from simple to major ones that could impact your vehicle's overall drivability.
One of the very common problems that your vehicle might encounter during the combustion process is referred to as backfiring. This term indicates a severe problem. When it happens, you must consult your mechanic immediately to figure out the issue before it gets more complicated and impacts significant components.
This article provides all you need to know about the concept of backfiring, the main causes, repair options, costs, and more!
What does it mean when your car backfires?
Understanding what it means when your car backfires is important because it helps you get a sense of how complicated and severe the problem is. And it also gets you to expect what troubles could happen and what could go wrong if you ignore this problem.
If you don't already know, the vehicle's combustion process must happen within the cylinders because these cylinders are put under pressure all the time to get the airfield mixture to ignite properly without any issues and therefore produce the energy that your vehicle is expecting.
Due to a variety of reasons, the combustion process could happen outside of the cylinders. When this combustion process finishes, it produces many extremely hot and pressurized gases, which means lots of trouble in the surrounding components.
Thus, whenever you experience any related issues to vehicle backfiring, you got to take it seriously and consult your mechanic as soon as possible because, in some scenarios, you might not be able to drive your car, and you might deal with complications that could mean losing the entire vehicle.
What causes engine backfiring?
As you might notice, a car backfiring is a severe issue and could lead to many complications you don't want to deal with. That's why it's critical for you as a driver to familiarize yourself with the different causes of an engine backfiring so you eliminate them as much as possible.
Typically, when your car experiences black fire income all, there is one of the following causes happening:
1. Too much fuel
The first and most important reason that could cause your vehicle to backfire is when you have a situation referred to as vehicle running rich. This is because your vehicle expects a specific amount of air and fuel to heat mixed to generate the combustion process and create energy.
When there is too much fuel inside the cylinders, that's what's called the engine running rich, which means it has too much fuel. When there is too much fuel, the combustion process will not be complete, and that's why the remaining fuel will burn and cause backfiring.
The scariest thing about this backfiring situation is that you'll hear an extremely loud popping sound while driving your car. If you've never experienced this situation, it can be extremely scary and cause you to panic and take the wrong actions. That's why you must eliminate this situation from happening and take care of any reason that could result in using too much fuel in your vehicle than needed.
2. Troubles with engine timing
The second thing you should focus on is the engine timing. As we mentioned earlier, the combustion process is extremely precise, and everything must happen at the right time.
The cylinders should receive the air and fuel mixture along with this park at the right time. When anything doesn't happen at the right time, you can easily deal with engine backfiring, which will be associated with the extremely loud noise we talked about.
When the spark is not sent at the right time, and when the air-fuel mixture is not ignited when it's inside the cylinders, the combustion process will happen outside the chamber. So, for example, it could ignite when the exhaust valve is opened, causing the backfiring.
3. Damaged distributor cap
In addition to the two previously mentioned causes, you cannot easily deal with engine backfiring if you have minor problems like cracks in the distributor cap.
Note that this situation doesn't happen and all cars. It is only designated and specified to vehicles with no ignition coils within their spark plugs. Therefore, check your spark plug system and determine whether it has an ignition coil or distributor cap.
If you confirm that your spark plug has a distributor cap, you must regularly inspect it and confirm it doesn't have any cracks. Sometimes referring back to the vehicle's owner's manual would be a great idea to get a sense of how often you should replace those before they get cracked and cause car backfiring.
4. Troubles with the spark plugs wires
Finally, your spark plugs could be a potential reason for the car backfiring that you're experiencing. For example, if carbon is built up on the spark plug wires, it can easily lead to issues with the spark timing, causing your car to Backfire.
Therefore, we highly encourage you to inspect your spark plug wires and replace them if they don't look as good to you. Then, you can check with your mechanic and have him thoroughly inspect all these spark plugs to confirm that they're all in good shape.
Your manual should tell you how often you should replace these spark plug wires. However, sometimes you might be experiencing problems with carbon building up and tracking on the spark plug wires before the due date, and that's why you are mechanics responsible for telling you about what's going on and determining whether you were backfiring is happening because of the spark plugs or something else.
What does a car backfiring sound like?
Some people get confused about what a car backfiring sounds like. You must understand what it sounds like because it helps you determine the problem and take the right action before things get severe. Incorrect typically, a car backfiring is more like a gunshot that is sometimes associated with fireworks thrown.
The backfiring sound is loud enough for you to detect it, but it's not super loud, so if you feel that there is some loud noise coming out of your vehicle, step back and do not ignore it because it could be a sign on backfiring. The more you wait on the problem, the louder these noises get, and the more severe things get.
Can a clogged fuel filter cause a backfire?
Sometimes it could. If you don't already know, the fuel filter is responsible for filtering any contaminants or debris. Ensure that the fuel inside the cylinder is clean enough and ready for the combustion process.
Over time use, this filter gets clogged partially or completely. Depending on the severity of the clog, your engine's combustion process can be impacted. For example, if the fuel filter is severely clogged, the engine will not receive the amount of fuel expected, and it will run lean. In this happens, it can easily lead to problems with igniting the airfield mixture outside of the cylinders, causing the backfiring.
That's why even if the fuel filter replacement sounds like a very simple repair, you must do it at the right time to prevent these extreme complications you never want to deal with.
Can a fuel injector cause a backfire?
Like the clogged fuel filter, anything that has to do with the fuel delivery could easily lead to a backfire. Whether this problem has to do with the fuel injector, the fuel pump, vacuum leak, and others, it can easily get you to a point where you hear this loud noise coming out of your car, which could be extremely scary.
Therefore, as we always like to say, whenever you're dealing with any problem in any system in your car, take care of it immediately and do not wait because it will eventually impact other components and get you to a point where you might lose the entire vehicle.
Your vehicle is a great and huge investment, and it's not worth wasting it just because you forgot to replace the fuel filter or inspect the fuel injectors.
How much does it cost to fix a car backfire?
Depending on the root cause of your car back, your prices can differ significantly. However, automotive experts mentioned that you could protect somewhere between $95 and $200.
Of course, repair costs can pile up significantly if you ignore the problem sometimes because the more it happens, the more gets complicated. In addition, the more it will impact other components that could be more expensive, including those associated with the engine's sensitive components.
Therefore, whenever you notice any loud bang or popping sound coming out of your vehicle's exhaust system or close to the engine, you must talk to your mechanic immediately and explain to him that you suspect it's in that firing.
Is it worth fixing a car backfire?
As we mentioned earlier, fixing the backfiring is not very expensive and can go up to $200. However, if the problem got more complicated and if it impacted some severe sensitive components, then that's where you must step back and evaluate the situation carefully.
If you realize that repair costs are piling up and getting close to your vehicle's value, it might not be worth fixing this car and you should sell it instead and purchase our vehicle.
