Did you clean the throttle body? The portion around the throttle plate and idle adjust screw air passage should be clean and if the idling speed is too low at operating temperature. turn the idle speed adjustment screw counterclockwise slightly to increase the idling speed. Do not turn too much at a time and if the idling speed seems slow to response to change. Turn engine off and restart to see if the idling speed changes.
