A sputtering tailpipe typically indicates incomplete combustion in the engine, often caused by fuel system issues, such as a clogged fuel filter or faulty fuel injectors. It can also result from ignition problems, like worn spark plugs or malfunctioning ignition coils. Additionally, exhaust system blockages or issues with the oxygen sensors can contribute to this sputtering sound. Addressing these underlying issues is crucial for optimal engine performance and emissions control.
Timing issue, poor ignition.
