My 2000 honda civic gx got stolen, so I would remove battery cable nitely to avoid this from happening again. Took it to get smogged everything passed except smog tech can't get any reading from my computor. Mehanic says to keep driving it and it should reset but its been 2 months. I drive a natural gas vehicle and can't get it to pass smog. I am so frustrated cause my extension from dmv has expired HELP!
