Why does my 96 integra ls shake a little when accelerating in first and second on 1996 Acura Integra

Sometimes it does it sometimes not but more then most previous owner hit something and knocked the alignment off but I had it fixed

it could be many things, check engine mounts, check the fuel injector, check fuel pressure, it could be your alignment and suspension also
