Slight Throttle Hesitation! What can cause it?

dirty injectors..........could be tons of things......................if it is MA check into that.............some times when they go you get bad response and some times they dont even run at all........best accurate info anyone can give you is look into fuel and spark and you will find your problem.
 
Cars an 88 so no Mass Air. "YET". Throttle body is brand new so it can t be dirty. However i still have stock injectors. I dont wanna buy a set of new 19 lbrs though, i was hoping to just convert to mass air and get new 24 lbrs with that. Hopefully they will hang in there a while more. Could be the spark to. I just bought new spark plugs like 3 days ago, but the dizzy is original stuff to, as well as the coil.
