rpm bounce?

I just finished putting my stock ls motor back into my 97 integra. The problem I am having is when I am cruising at around 3k rpms I noticed that my rpm gauge bounces up and down. The car also feels like it shudders a little bit, kind of like its missing almost. Its not real noticable, but enough. Anybody have any ideas what this could be?

dirty injectors cause hesitation and almost feels like a mis-fire under partial throttle conditions'......if you run out of ideas id pull them and clean them up a tad and re-install'
