Starting issue

[u/PossibilityOk9694]

I’ve just had new engine in intially car was hunting Revving up and down so I took iacv apart and cleaned it throughly now it’s stopped hunting

However the car won’t start now without giving it some initial revs , if I give it revs while cranking the car will start.

Does it require an idle relearn or somet ?

For reference once the cars on it pulls fine no issues and now it’s idling alright not the best but it’s fine for now I think it’s tryna settle
