The usual things like cable hanging up, butterfly sticking open.  People 
often say 'vacuum leak' but whilst that *will* cause a higher idle for a 
given butterfly opening, the idle screw should always be able to slow the 
idle down to a stall even with a vacuum leak, 'cos the engine can't run on 
air alone.  The only time that won't be the case is if there is an 
alternative path past the *closed* butterfly, which could happen if the 
butterfly spindle and bushings are very worn.
