if it is a vortec, there is a fuel line under the upper intake that goes from the manifold to the injector. check it for cracks and leaking or the injector itself.

EGR Valve

Rough idling is whenever the vehicle's motor "misses" or does not fire causing an imbalance and a loss of rotation reducing the motor's power and causing excessive shaking.
