Top Reasons Why Your Subaru Stalled

Subarus are reliable and durable cars, but like any car, they can experience issues over time. One common problem Subaru owners may encounter is stalling. Stalling can be frustrating and even dangerous, especially if it happens while driving. In this article, we’ll discuss the top reasons why your Subaru may stall and how to prevent it from happening.

Dirty Air Filter

The air filter in your Subaru helps to prevent dirt, debris, and other contaminants from entering the engine. Over time, the air filter can become dirty and clogged, which can restrict airflow to the engine and cause it to stall. To prevent stalling due to a dirty air filter, it’s important to replace the air filter regularly, usually every 15,000-30,000 miles.

Bad Fuel Pump

The fuel pump in your Subaru is responsible for delivering fuel to the engine. If the fuel pump is faulty or failing, it may not be able to deliver enough fuel to the engine, which can cause it to stall. Signs of a bad fuel pump include difficulty starting the engine, low fuel pressure, and engine misfires. To prevent stalling due to a bad fuel pump, have it checked and replaced if necessary.

Faulty Ignition System

The ignition system in your Subaru is responsible for providing the spark that ignites the fuel in the engine. If the ignition system is faulty, it may not be able to provide a spark, which can cause the engine to stall. Signs of a faulty ignition system include difficulty starting the engine, engine misfires, and poor acceleration. To prevent stalling due to a faulty ignition system, have it checked and repaired by a professional.

Clogged Fuel Injectors

The fuel injectors in your Subaru are responsible for delivering fuel to the engine. Over time, the fuel injectors can become clogged with dirt and debris, which can restrict fuel flow and cause the engine to stall. Signs of clogged fuel injectors include rough idle, poor acceleration, and engine misfires. To prevent stalling due to clogged fuel injectors, have them cleaned or replaced as needed.

Dirty Throttle Body

The throttle body in your Subaru controls the airflow to the engine. Over time, the throttle body can become dirty and clogged, which can restrict airflow and cause the engine to stall. Signs of a dirty throttle body include rough idle, poor acceleration, and engine misfires. To prevent stalling due to a dirty throttle body, have it cleaned or replaced as needed.

Faulty Mass Airflow Sensor

The mass airflow sensor in your Subaru measures the amount of air entering the engine and sends this information to the car’s computer. If the mass airflow sensor is faulty, it may not be able to accurately measure the air entering the engine, which can cause the engine to stall. Signs of a faulty mass airflow sensor include difficulty starting the engine, poor acceleration, and engine misfires. To prevent stalling due to a faulty mass airflow sensor, have it checked and replaced if necessary.

Conclusion

Stalling can be frustrating and even dangerous, especially if it happens while driving. The top reasons why your Subaru may stall include a dirty air filter, a bad fuel pump, a faulty ignition system, clogged fuel injectors, a dirty throttle body, and a faulty mass airflow sensor. To prevent stalling, it’s important to have your car regularly maintained and inspected by a professional. Regularly replacing the air filter and cleaning the throttle body and fuel injectors can also help prevent stalling.
