What could cause low idle on 2006 gmc envoy?

Low idle on a 2006 GMC Envoy could be caused by several factors, including a dirty or malfunctioning idle air control valve (IAC), vacuum leaks in the intake system, or issues with the throttle body. Faulty sensors, such as the mass airflow sensor (MAF) or throttle position sensor (TPS), can also contribute to irregular idle speeds. Additionally, problems with fuel delivery, such as a clogged fuel filter or failing fuel pump, might result in low idle performance. Regular maintenance and diagnostic checks can help identify and resolve these issues.
