Are you saying this only happened after you changed the intake or did it always idle rough and you never noticed it til now? All mirage engines shake a lot at idle but it's not really noticeable when you're sitting in the car, but open the hood with it running and some people might think something is wrong. It's normal for the engine to shake around.
