The problem I am having is that after the car warms up I get detonation below 3000 rpm.. cold she runs fine and noiseless.. sounds like timing to me? since the o2 sensor, egr valve cap rotor plugs and wires are all new...

See if the EGR is working correctly, and that the passages are clear. Have you tried higher octane fuel just to verify that it is pre-ignition you hear? It sounds like it is related to the engine going into closed loop operation, but I'm at a loss to explain why it would do that. Overly lean mixture, high operating temp or timing advance are the most likely causes, you're right there.
Did this just begin happening all at once, or has it been working up to it for some time? Does ambient temperature have any effect? Have you verified the cam timing? Is it possible the belt could have slipped? Is power normal otherwise?
