Too Afraid to Ask

Backfire is when the engine makes a loud popping noise because the fuel ignites at the wrong time or place. It usually happens when there's a problem with how the engine is working.

Technical Definition

Backfire occurs when the fuel-air mixture ignites outside of the combustion chamber, often due to incorrect timing or a misfire. This can result in a loud popping sound and can indicate issues with the engine's ignition or fuel system.
