A 1996 Subaru Legacy may not go to low idle due to several potential issues, including a malfunctioning idle air control (IAC) valve, vacuum leaks in the intake system, or problems with the throttle position sensor (TPS). Additionally, a dirty or failing mass airflow sensor (MAF) can disrupt the air-fuel mixture, affecting idle performance. It’s also possible that a faulty engine control unit (ECU) could be hindering proper idle control. Diagnosing these components can help identify the root cause of the idle problem.
