I have this '88 Civic that has a '90 Civic motor in it. I went to get it smoged, so I can sell it, and they're telling me it has to get bard. I got it smoged in October with no issues, but now I'm having issues. I have all paper work for the motor and it passes the sniffer test no problem. What parts will I need to get it to pass? Do I need to get everything done before I see the smog ref or will they tell me what I need to do?
