E39 528i/5 sport temporary rough running

My cousin just bought yesterday morning a 528i/5 after hearing everything I had to say about bimmers, and loves it. Tonight he decided to do 0-60 as fast as he dared for the first time without launching (he's a very conservative driver). Never got past 5500 rpms in each gear. After doing this, he said the engine started running rough immediately, perhaps misfiring, at all rpms. Pulled over, and the idle was irregular and varied from 300-1000. He turned off the car, called me, popped the hood, and couldn't find anything wrong. Started the car back up again and the engine ran fine, no roughness at all. Any ideas what might have happened here?
