Default Vibration

For some reason out of the blue one day, when my car revs to about 2100 to 2300 i have a slight vibration and can't find it for the life of me! Anybody have any clue on what it could be? Ive changed the plugs many times since then and its still doing it! Possibly wires causing a flutter?

Whats up man, Im in tyler too! Is this happening under load? Auto car? m6? I'm assuming where not talking about a driveline type of vibration since your checking ignition stuff...?

It does it any time. It's a auto now and used to be a 6 speed but it still had this problem with the 6 speed. Im starting to think that its probably just vibration from the exhaust somewhere. It doesnt seem to be driveline related since it only does it at a certain rpm in any gear and not speed related. All though i cleaned up my tune a little bit today and it seemed to smooth it out quite a bit. Who knows!
