uh oh.. engine knock?

I recently replaced my timing belt and now after i stop at a red light and the engine returns to idle there is a knock that seems consistant with the rpm. A little throttle and the sound goes away. I havn't been able to jump out and find the sound because it doesn't happen every time. It was also doing this prior to the old timing belt snapping; not sure if they're even related. Any thoughts fellas???

Check the tension on the timing belt, the "knock" may be the belt slapping against the timing cover. If it's tight, use a mechaninc stethoscope(sp?) to locate the source of the knock.

The tension seems good ( about 3/8sth of an inch deflection). I can hear the sound through the plastic cover and through the brand new belt tensioner. It shouldnt be the tensioner since its new though, unless i have too much belt tension maybe?
