2000 Honda civic failed emissions due to high hydrocarbons what are all the possible reasons for this?
High levels of hydrocarbon is normally caused by malfunctioning catalytic converter. Its function is to convert hydrocarbon and carbon monoxide to water and carbon dioxide. Try slapping the converter (when it is cold) and listen for any loose and rattling noise inside. Loose and rattling noise is a sign that the beads of catalyst materials have come loose and replacement of the coverter is necessary..
