Idle RPM issues when AC is in operation during driving and when stopped in place. Had the vehicle checked several times by Ford Tustin during warranty coverage. Each visit, they were unable to locate issues noted.

To this day, When vehicle is idling in driveway, AC is turned on and rpm drops to 600 rpms and at times wants to stall.

AC functions perfectly, so uncertain how to proceed on engine RPM issue.

Thanks much, All!
