Ok, I dropped a Y8 in my 90 DX CRX. I wired it to multi poin OD-0 using a ZC ECU. I finally got it dropped and the car to turn on. but it runs like straight ass. it wont go past 2100 RPM and dies out and sputters. I changed the spark plugs, wires. Dist. fuel pump cleaned the lines. fuel filter. .. still runs like ass. is there any other things that you think could be wrong? vacuume leak? FPR? I really have no idea anymore. I am by no means that great with cars. any ideas or anything is appreciated. thanks.
