Does anyone know where I can get a picture of how the egr tube fits in to the throttle body. Mine does not fit snug and continually leaks air. Is there a sleeve or something that goes around the egr tube and inside the throttle body because the inside diameter of the throttle body does not fit snug to the outside diameter of the egr tube. This tube was originally removed by garage for throttle body cleaning and the car has never idled or ran properly since
