I have just bought a 91 Civic hatchback and am trying to figure out the engine. The tag under the hood says the caris a Civic 1500 hatchback. I am assuming that is a 1.5 L engine. Also the top of the engine says that it is a 91 cid 16 valve dual point programmed fuel injection (PGM-FI). I see d16a, h22, etc. but can't find any of those numbers on mine. please help.

 

read this thread, it's very easy to figure it out
