- Misfires: A misfire occurs when the spark plugs in your engine are not firing properly, which can cause the check engine light to blink. This can be caused by a number of factors, including faulty spark plugs, ignition wires, or a distributor cap.
-Oxygen Sensor Issues: The oxygen sensor monitors the amount of oxygen in the exhaust gases and sends this information to the engine control unit (ECU). If the sensor is faulty or damaged, it can cause the check engine light to blink.
-Faulty Catalytic Converter: The catalytic converter is responsible for converting harmful pollutants in the exhaust gas into less harmful substances. If the catalytic converter is failing or damaged, it can cause the check engine light to blink.
-Coolant Temperature Sensor Issues: The coolant temperature sensor monitors the temperature of the engine coolant and sends this information to the ECU. If the sensor is faulty or damaged, it can cause the check engine light to blink.
- Transmission Problems: A blinking check engine light can sometimes indicate a problem with the transmission, such as low transmission fluid or a faulty shift solenoid.
It's important to note that the exact cause of the blinking check engine light in your 1998 Subaru will need to be diagnosed by a qualified mechanic. It is not recommended to drive your vehicle if the check engine light is blinking, as this could cause further damage to your vehicle.
