    turn up your stereo or get bias tires :wink1:



    probly carb air intake or not sealing right or belt loose... stick your head in the engine compartment while its running then start putting your hand on things to seal

    If its the 89-91? K5 in your av you are talking about. Check the Throttle body base gasket. They leak and make a nice whistle when they go bad. Also can cause some idle issues.
    Vaccume leaks? Check all your vaccum lines ect
