When stopped at a stop sign my car spits and sputters what could be wrong?

If your car is spitting and sputtering at a stop sign, it may indicate issues with the fuel system, such as a clogged fuel filter or failing fuel pump, which can disrupt fuel delivery. Other potential causes include ignition problems, like worn spark plugs or ignition coils, or a malfunctioning air intake system. It’s also possible that there could be issues with the engine's sensors, such as the mass airflow sensor. It's advisable to have a professional mechanic diagnose the problem to ensure safe and reliable operation.
