So I'm back again, i have a 93 civic so with 185k miles on it. I changed the fuel filter and began having a weird starvation issue, i took off the fuel line that goes to the fuel rail and cleaned that out. I decided to replace an injector while i was in there because it had been smashed. After that it wouldn't start at all and i discovered gas on the spark plugs, so i pulled them all and replaced them, and figured i should replace all of the injector seals. Today i got it to start but it runs rough, there's a decent tap, i know it's not a bearing or a rod because I've heard those knocks before. I'm convinced it's something with the fuel system, also when it's running if i give it gas and let off it stalls and then hesitates starting back up, any help is appreciated!
