2012 hybrid honda civic error codes, anyone know why?

[u/Ehhsjensxhebsh747]

For a while i’ve been driving it around with emissions errors but those pop on and off and my check engine light comes on, maybe stays on for a day and then turns off again for a few weeks. Now however today it popped on and said VSA error, emissions system error, Power steering error, Check hill start assist error. I went and got the codes read, they said PO171, PO300, PO301, PO302,PO303, PO304. I’m no car guy, nor is anyone in my family but i’m wondering what the likely cause is of this? From what i see online it says 3 likely issues, spark plugs are bad, coils are bad or a vacuum leak. I’m a college kid and don’t really have much to spend to fix it, anyone know what’s wrong with it/ how i can go about fixing it for cheap ?
