After adjusting my air mixture screws, I noticed now when I pull up to a light and stop, the car will shake CRAZZZY like!! but if I throw it in neutral, no problem, but in drive stopped at a light with the brakes applied, its crazy bad, soon as I let off them, no problem. Vacuum line? Im stumped, please lets not say its the damn torque convertor. ahaha well I guess basically Im looking for an answer, just thought its weird out of no where this problem has arisen.
