(Fuel System)
Fuel pump: A weak or failing fuel pump may not be able to provide sufficient fuel to the engine, causing it to stall.
Fuel filter: A clogged fuel filter can restrict fuel flow and lead to engine stalling.
(Idle Air Control (IAC) Valve)
The IAC valve regulates the amount of air that bypasses the throttle plate when the engine is idling. A faulty or dirty IAC valve can cause the engine to stall.
(Throttle Body)
A dirty throttle body or a faulty throttle position sensor can affect the air-fuel mixture and cause the engine to stall.
(Vacuum Leaks)
Vacuum leaks can cause the engine to run lean, leading to stalling.
(Electrical Issues)
Faulty sensors or electrical connections can provide incorrect signals to the engine control unit (ECU), resulting in engine stalling.
Battery or alternator problems can affect the electrical power supply to the engine and cause stalling.
(Mechanical Issues)
Mechanical problems such as worn-out engine components or a faulty ignition system can also lead to engine stalling.
Diagnosis:
Pinpointing the exact cause may require diagnostic testing using specialized equipment. If you lack the knowledge or tools, it is recommended to have the vehicle inspected by a qualified mechanic or automotive technician to properly diagnose and fix the issue.
