Rough Idle. 1/8" gap between the throttle body and the upper intake manifold.

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.
