slight knock when cold 95 camaro in sig, motor has 30 k. When I started it this morning I think it was knocking slightly when warming up. After 2-3 mins I drove to school (half a mile). While driving I heard no knocking and once I parked, the car idled nice and smooth. I don't know whether it would throw a code if there was a knock problem but it didn't. Should I be worried?

Na, I wouldnt be worried. It isnt all that uncommon for newer motors to knock when cold. They keep putting shorter and shorter piston skirts in these motors. That is most of the knock heard. 5.3L truck motors are really bad for this. Also the oil is thicker, so you may hear some lifter tick. I wouldnt be concerned unless it is really loud or doesnt go away after a few minutes of driving.
