how to fail smog check

Asked by Feb 15, 2017 at 07:16 AM about the 1993 Honda Civic del Sol 2 Dr Si Coupe

Question type: General

How do I fail the California smog check? My car is old and I want to retire it and
get the $1000 from the state of cal. But it fail due to a fuel cap inspection, not
emission. This does not qualify me for the $1000. Can I put something in the
gas tank to make sure that it will fail the emission test?
