The fluctuating RPM of a 1991 Eagle Talon while idling can be caused by several factors, including a vacuum leak, faulty idle air control valve (IAC), or a dirty throttle body. A vacuum leak can disrupt the air-fuel mixture, leading to unstable idle. Additionally, if the IAC is malfunctioning, it may not regulate airflow properly, causing erratic RPMs. Lastly, carbon buildup in the throttle body can hinder air intake, contributing to idle instability.
