A stutter in a 1990 Nissan 240SX can be caused by several factors, including fuel delivery issues such as a clogged fuel filter or failing fuel pump, which can disrupt the fuel supply to the engine. Ignition problems, like worn spark plugs or faulty ignition coils, can also lead to misfires and stuttering. Additionally, issues with the air intake system, such as a dirty air filter or a malfunctioning mass airflow sensor, can affect engine performance. Lastly, vacuum leaks or problems with the engine's electrical systems can contribute to this symptom.
