First thing I always check with rough idle are the vacuum hoses.

His problem is with in computer not bumping the idle rpm up. I am not sure how that vehicle is setup to do it.

Its not a vacuum problem. That vehicle may not even bump the idle up. It may just disable the alternator until the engine speed picks up. He needs some one with a shop manual for the car or alldata
