Heather Moser (, Massachusetts) - 1997 Volkswagen Cabrio
An engine/fuel question. After the car warms up and she comes to a stop, the RPMS will race between 0 and 1k and the engine shakes. She's tried putting better fuel in it, and it doesn't help. Could have a vacuum hose leak. Take it to a mechanic. he should be able to find it quickly.
