Lightbulb How do you Idle down RPM's on '86' 420SEL?

How do you idle down the RPM's on an '86' 420SEL? When I start the car, it is idled at 11,000. I read in a book somewhere that it should be around 6,000. The car seems to burn allot of gas. I mean, I do realize this is a large and older sedan, but when I tried to figure the mileage per gallon of gas, it's awful. Where under this great big hood do I look?? Can it be idled down without taking it to a mechanic?
