    It would be easier if we could hear the noise. Do you have someone you trust to help identify the sound.

    I am having someone look at it today, but over the weekend one person said it could be the flywheel and another said the catalyst converter. I wont know until later on today. But like I said it only does this when I press on the gas pedal like something is rattling underneath.
