Car Popping Noise from Exhaust when Accelerating | What to do?
One of the first lessons in driver’s education is that any unusual sound coming from a car should be investigated. Even if you only hear something once and never again, there could be a problem to solve. While accelerating or immediately after, a popping noise is common to listen to while driving.
What’s making that noise? Is it simple to repair?
Is it necessary to take the engine to a mechanic when it starts popping? The answers to those questions can be found further down.
Popping Noise on Acceleration?
When you hear popping or crackling sounds coming from a vehicle, it is usually the result of unused fuel exiting the engine. It is ignited by the hot exhaust system, resulting in unwanted noises. Because of an overrun, it frequently occurs after hard acceleration, right when the throttle is let go.
When you accelerate quickly or let off the gas pedal soon after a long drive, you’ll hear a popping sound caused by an acceleration problem. Some vehicles may lurch or hesitate during that time, but functionality is restored almost immediately.
Because some unspent fuel is sent along the exhaust route, the popping sounds may appear to come from the car’s center rather than the front. It can even be compared to the “backfire” that occurs. If your car is constantly backfiring or making a popping noise when you accelerate, it may be time to have the problem professionally diagnosed.
Although most problems are minor, predominantly if you’ve driven the vehicle hard, there’s always a chance that the repetitive sounds are an indication of something more serious.
What Else Could Be Causing the Popping Sound?
The front suspension may have ball joints if you have an older vehicle, especially a truck. When going over a bump in the road or turning a tight corner, these components can sometimes make a popping sound.
If you’ve been performing your vehicle’s regularly scheduled maintenance, these sounds are usually nothing to be concerned about. It’s the joint’s regular activity.
If the popping occurs around each curve or bump, you should have the parts checked out because this could indicate a worn-out component.
The popping sounds that occur when turning sharply or driving over a pothole can also indicate that your shocks or struts need to be replaced.
How to Troubleshoot the Popping Noises from Your Engine
The popping sounds coming from the engine compartment could be caused by various factors. After a few months of driving the vehicle, you’ll have a sense of what’s “normal” and what’s “unusual.”
You may be getting a heavier knock because you’re accelerating while carrying a heavy load. As the engine RPMs rise or fall, some noises become louder or quieter.
Knowing how the engine works can help you figure out which parts are causing the annoying popping sounds. The best way to determine a result is to use a process of elimination to identify the issue.
These steps can help you get started troubleshooting your computer to figure out what’s wrong.
How your engine works
The internal combustion system uses flammable liquids, air, and controlled explosions to power your vehicle. Backfires occur when this system fails to function correctly, which is why it’s critical to understand how the engine works to determine why your car is backfiring.
Here are the fundamental steps your internal combustion engine takes to convert fuel and air into horsepower:
Step#1:
Begin by putting the vehicle in park. You can also use the neutral gear while the emergency brakes are engaged.
Step#2
Start the engine. You can open the hood after you’ve turned the key or pressed the button.
Step#3
Attempt to pinpoint the general location of the popping sound. It would be best to inspect the belts and pulleys to rotate freely. Another common issue is the fan colliding with the shroud as it spins.
Step#4
Examine the radiator cap to ensure that it has a proper seal.
Step#5
Listen to the engine noise carefully. You’re listening for any clacking or knocking noises. If you have valve covers, you should listen to them as well. Top of the intake manifold Sounds detected here may indicate a problem with your tappets or hydraulic lifters.
Step#6
The exhaust valve closes, enabling smoke and combustion residue to flee through the tailpipe. The entire process is repeated while your engine is running, with multiple pistons and fuel tanks working to make the tires on your bus (or car) go round in.
Additional Sounds coming from your Vehicle
Although popping during or immediately after acceleration is not uncommon, it is feasible that it’s not how you will indeed describe the sound. Because noise perception is relatively objective, here are a few other issues you may run into when trying to diagnose a problem with your vehicle.
How to Solve the Engine Popping Problem
If the only problem you’re having is that the engine pops when you accelerate hard and then suddenly let up on the gas, you might not need to do anything. This issue arises in many vehicles because fuel is distributed to generate combustion for forwarding movement.
If you hear an unusual sound, the first thing you should do is to check your heads-up display. If the Check Engine light illuminates, your onboard computer may enter a mode that restricts the amount of power going to your drivetrain. In this case, your next stop should be at a mechanic’s. If the popping sounds are muffled or accompanied by a low rumble, pull over somewhere safe to cool down the engine. It may take a few minutes once you’ve gained access to areas under the hood.
Final Verdict
If nothing is visible, restart the engine and listen for hissing or sucking sounds, which indicate an air leak.
The vast majority of problems are do-it-yourself. You may need to replace your spark plugs or wires to eliminate the sound. If your fuel filter is faulty, replacing it with a mechanic may be more straightforward.
If everything appears to be in working order, your fuel injectors could be the issue. If they become clogged, your vehicle will not send enough gasoline to the engine, resulting in poor engine performance.
