Engine Performance problem
2003 BMW Z4 6 cyl Two Wheel Drive Automatic 60000 miles
every now and then when starting the engine idle surges up and down. After restarting the idle is fine. Again there is no warning and only after starting, out of nowhere, the idle goes crazy and car runs rough but problem ceases after restart. No problem until it happens again maybe a week or two later or maybe even longer.
