2002 Camaro z28 6 speed... at idle the car has a light thud feeling but the car idles where it should be almost like a misfire but does not throw a code of detecting a misfire I have replaced the plugs and new wires thinking it would have helped the problem but did not could anyone help me diagnose it a little better or point me in the right direction on what to look at next?

If plugs aren't the problem, I would then concentrate on the coils.
