idle never goes below 650 even with AC off and engine is warmed up

What is your question?

idle never goes below 650 even with AC off and engine is warmed up. Will go to 750 with AC on. Engine runs smooth and seems normal other than idle speed. I have checked the throttle valve and it looked good. Cleaned some gum out but not much. Pulled battery to reset computer. Idle still at 650 with no AC. russ

How long has your 2008 Lexus LS460 had this problem?

about a week. Just bought the car.
