Why does a 1991 camaro rs v6 idle bad after warm?

A 1991 Camaro RS with a V6 engine may idle poorly after warming up due to several potential issues. Common causes include a malfunctioning idle air control valve (IAC), vacuum leaks, or problems with the throttle position sensor (TPS). Additionally, a dirty or failing mass airflow sensor (MAF) or fuel delivery issues could also lead to poor idle performance. It's advisable to perform a diagnostic check to pinpoint the exact cause.
