Every time there is a stop light, the car vibrates and shakes unless I step on the gas a little bit. I'd love to fix this.

    You state 1/8" gap between throttle body and intake. Maybe I'm reading it wrong , but is the throttle body loose? Is the gasket gone? That would definitely cause problems.
