It starts sometimes and runs smooth for like 15 seconds n starts missing after that sometimes it misses from the start. Why does it run smooth for the 15 seconds sometimes?

Year of vehicle? Any engine mods? And it was doing this before and after all the parts you replaced?

Are there times when it won’t start at all? Aside from misfire, are you able to drive it? Have you scanned for codes, checked fuel pressure?
