Abit of both tbho mate but pops and bangs does use more fuel yes as its thumping fuel in on over run instead of leaning out.
As factory your car stops injecting fuel when you lift off the throttle, or coast down hill in gear etc..
Why do cars crackle and pop?
That crackle comes from excess, unburnt fuel burning and exploding in the exhaust pipe. Everything from a light crackle to the full gunshot-like sound of a “bang-bang” Anti-Lag System (common in Rally cars) to shooting flames are all caused by the fuel burning in the exhaust that comes with running rich.
Is it bad to make your exhaust pop?
Pretty normal in moderate amounts, especially for a performance car. It’s unburnt fuel hitting the hot exhaust piping and detonating. Some modern cars (Jaguar F-Type) are set to do this purposely to enhance the exhaust tone. … Unburnt fuel could cause wear to your Catalytic converter, but I think that’s about it.
Can a backfire damage an engine?
An engine backfire occurs whenever the air-fuel mixture in your car combusts somewhere outside the engine’s cylinders. This can cause damage to your car’s exhaust or intake if left unchecked — and it also means that your car’s engine isn’t making as much power as it should, and is wasting lots of fuel.
Is popping bad for your car?
However, on cars that are supercharged or naturally aspirated, the snap-crackle-popping a lot of us are fond of isn’t quite as easy to justify. In fact, it hurts your fuel economy, forces your revs to hang high longer as you let off the gas, and inhibit engine braking.
Why does my exhaust crackle and pop?
The heavily retarded ignition also means much of the combustion happens with the exhaust valves open (in fact within the exhaust system), and much of the fuel is ignited by the hot exhaust and/or catalytic converter, hence the burbles, pops and crackles you hear from your tailpipe.
Can bad spark plugs cause backfire?
Another possible cause of your backfire is a spark plug refusing to “spark” when the exhaust valve opens. If the air/fuel mixture has become too rich, unburned fuel is left in the exhaust system. The misfired spark plug ignites the rich air/fuel mixture, causing a loud “bang” in the tail pipe.

Can a clogged fuel filter cause backfire?
Symptoms of a clogged fuel filter result to the fuel starvation in a car. … Fundamentally, dirty fuel filters cause the car to backfire since it is the explosion produced by the running of the internal combustion engine that in most cases occur in the induction system.
What makes a car pop?
In some high-performance vehicles, when a driver shifts up and lets off the accelerator, the engine has a moment of running rich. This causes an incomplete burn which causes the fumes to explode in the exhaust system along with an audible pop or bang sound.
What does it mean when your exhaust pops?
Running too rich If your engine is getting more fuel than it needs, a rich fuel to air ratio is the result. When your car has leftover fuel in the exhaust and the cylinders, that fuel explosively burns and creates a loud popping sound.
