Car in question is a 2000 S70 SE with 47,500 miles. Today in the parking lot. I <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0"> turned the key and the car started. The engine reved to 1500 as it always does and when headed back down to idle it passed idle and died. It did this four times before starting and running again. Drives fine runs fine nothing else seems wrong. This has happened one time before. Any ideas? Thanks in advance to all who respond.
