RPM IDLING HIGH

2003 Pontiac Grand Am • 2.4L V6 FWD Automatic • 148,000 miles

Doesn't do it all the time. RPM idles at start up 2500-3000 and stays. Changed the tsp/iac & thermostat control valve. There are no vacuum leaks.

Have you checked for vacuum leaks? Has the check engine light come on? Have you checked the temp sensor?
