Hi i have an nissa. Na20 the moter was recently done

What is your question?

Wen i exelerate evenly its fine but wen i put my foot down to the floor wen at idle its got like an hikup before it revs up

What makes this problem better or worse?

wen timing set at distributor

How long has your 1993 Nissan D21 had this problem?

since moter was done
