Hilux owners facing engine sputtering often trace the issue to fuel delivery problems, such as clogged fuel injectors o r a weak fuel pump, which restrict fuel flow. Ignition-related causes include faulty spark plugs o r coil packs, leading to misfires. Air intake blockages, such as a dirty air filter o r malfunctioning mass airflow sensor, can disrupt the air-fuel mixture. Some have also reported issues with bad fuel quality o r contaminated fuel affecting combustion. Diagnosing the exact cause through fuel system checks, ignition component inspection, and airflow sensor testing helps resolve the problem effectively.
