  1. Fluddering Sound on Start Up

    B5 Garage
    It happens very randomly. Once every few weeks. It happens about 5 seconds after the car has started. It almost sounds as if there was a hole in the muffler near the engine. It kinda gurgles? If thats the right word, for another 4 seconds and then goes back to smooth idleling. Ideas? 2002...
