How long since a tune-up? Any applicable trouble codes? If your saying the idle is too high, for testing, I block off the mouth of throttle body, it should kill the engine, if not, you got false air getting in there from somewhere? A vacuum leak? Also, You can check and clean anything that has to do with idle air system.

L-Series
