How do you adjust for rough idling in a 1997 Acura RL?

To adjust for rough idling in a 1997 Acura RL, start by checking and cleaning the idle air control (IAC) valve, as it regulates airflow during idle. Inspect the throttle body for dirt buildup and clean it if necessary. Additionally, ensure that spark plugs, ignition wires, and fuel filters are in good condition, as worn components can contribute to rough idling. If issues persist, consider checking for vacuum leaks or using a diagnostic tool to identify any trouble codes.
