might also pull the egr vlv, and see if it's cloged up....if so, do some "house keeping" and clean it & the mani with some carb cleaner. if I'm not mistaken, when they get sticky, the sensors will send a false signal to the ecu that the engine is running rich, and will lean it out some causing the high idle condition...also check for vac leaks, if one of the lines it off, or clogged, that might be causing the high idle as well...
** edit: well, maybe not a lean condition, but the sensors will send a false sig to the ecu, and thru w/e means of compensation, the engine idle speed is increased to make up for
w/e the root cause is...
