Why would a 1998 Olds Aurora stall out in idle?

A 1998 Oldsmobile Aurora may stall at idle due to several potential issues, including a malfunctioning idle air control (IAC) valve, which regulates the engine's idle speed. Other possible causes include vacuum leaks, fuel delivery problems, or a faulty mass airflow sensor. Additionally, issues with the ignition system, such as worn spark plugs or ignition coils, can also lead to stalling at idle. Regular maintenance and diagnostics can help identify and resolve these problems.
