    Default Vibrating noise when accelerating

    Hello, I have a question for anyone that might be able to help me please. I have a 2001 tahoe and when I accelerate normally I hear this annoying vibration that sounds like it could be a heat shield or something vibrating. Anyone know what this is?

    It is the heat shield on your muffler, seen this many times. You can cut it off or GM had big 'hose' clamps to put around themuffler to stop it.

    Thanx for the info. I will get under there and check it out. Think tin snips will work to cut it off, doubt there is room for a hack saw.
