Not an unusual problem. It's often caused by air leakage past worn throttle-valve bushings. Maybe other causes, too, that I haven't encountered.

Has it done it since the rebuild?
Are the butterflies centered in the bores?
Could be that one is not centered on the shaft or in backwards taper the wrong way? Partial open throttle
