Hello all I'm new here and was wondering if someone can help me out..ok here's the problem.
I have a 1986 bone stock grand national my step dad gave me.its been siting so we got all new gaskets for cause they were rotted out...but we noticed when you mash the pedal you get this sound like if you put pencils in a tin can..but if you slowly go on the gas it wont make that sound runing stock boost 15 pounds

Thanks
