* Idle air control valve (IACV) issue: The IACV is responsible for controlling the amount of air that flows into the engine when it's idling. If the IACV is faulty, it can cause the engine to stall when you come to a stop because it won't be able to provide enough air to keep the engine running.
* Throttle body issue: The throttle body is responsible for controlling the amount of air that flows into the engine when you press the accelerator pedal. If the throttle body is dirty or faulty, it can cause the engine to stall when you come to a stop because it won't be able to provide enough air to keep the engine running.
* Fuel injector issue: The fuel injectors are responsible for spraying fuel into the engine's cylinders. If a fuel injector is faulty, it can cause the engine to stall when you come to a stop because it won't be able to provide enough fuel to keep the engine running.
* Spark plug issue: The spark plugs are responsible for igniting the fuel in the engine's cylinders. If a spark plug is faulty, it can cause the engine to stall when you come to a stop because it won't be able to provide enough spark to keep the engine running.
* Vacuum leak: A vacuum leak can cause the engine to stall when you come to a stop because it will cause the engine to run lean (too much air, not enough fuel). This can be caused by a cracked or loose hose, or a faulty gasket.
If you're experiencing this issue, it's best to have your car inspected by a qualified mechanic so they can diagnose the exact problem and recommend the best course of action for repair.
