Your 2001 Nissan Xterra may stall at idle speed due to several potential issues. Common causes include a dirty or faulty idle air control valve (IAC), fuel system problems such as a clogged fuel filter or failing fuel pump, or issues with the engine's ignition system, like worn spark plugs or ignition coils. Additionally, vacuum leaks or a malfunctioning mass airflow sensor can disrupt the air-fuel mixture, leading to stalling. It's best to have a mechanic diagnose the issue for a precise solution.
