just got a 91 si with a b16a and it drove fine for the first 2 day, and then I was driving home and I was at a stop sign let the clutch out and it just died. So I got it off the road and it sarted up but every time I push the gas in the rpms would just go way down, so I would let off the gas and it would go back up. Well I got it home and I changed the fuel filter and drove it around and it did fine. I let it sit for all week and I took it out last night and I didnt get a block away and it was doing it again. Also it made a crazy sound sometimes when I try and start it like it was coming out of the intake. any help would be greatly appreciated
