with a good scanner you can drive the car monitoring the datastream and isolate the problem, or lack thereof, then investigate the mechanical failure further.
another thing is, since those cars are drive by wire, the ecu controls how much the throttle opens along with the idle. basically the idle air control valve is built into the throttle body. and since it is all electrical it could be failing....
however since it throws no code, and since the ecu controls the throttle body, it could also be a bad ecu. that's usually the last place to check though since there's no real test for an ecu other than trying a known good one, which would mean you'd have to get one from a junk yard so you wouldn't pay 234e32432424 million dollars at the stealership, however you'd need the new ecu to be reflashed to use it.
first thing i'd do is unbolt the cat and run open header and see if the car has power. that will deduce that as the culprit.
well actually the first thing I WOULD do is hook up the snapon modis scanner and look for pending codes, then monitor the datastream while driving it...but if you don't have access to a scanner then start with my first suggestion and unbolt the cat.
tell you what, do that then post back with your results.
