If anyone can help me with this one I'd appreciate it. I just installed a B16A2 into my 95 hatch and there's a knocking sound on start up and it isn't idling smoothly. When revving, the sound gets quieter, or at least stays the same, so I don't think that it's cylinder related. It seems to be running really rich also. I suspected a misfire, so I changed the plugs and wires, but no difference. There are no codes coming up, but the oil light is on steady. Any ideas out there??? Thanks in advance.
