Default idle revs up and down

So after i put a new engine in my 95 the idle revs up and down. It does it all the time. Only did it after the swap and it has the original sensors and stuff from the original IM/TB. I need help its damn annoying. Thanks in advance

Have you tried cleaning out your IACV? or if that doesnt work about using another one?
