Help ! Toyota Corola failed Emission Test
 

My 1994 Corola failed the Emission test. Nitrogen Oxide test - failed 576/648.
All other tests were well below limit. Anyone have any suggestions
on what the cause may be?

No Egr, Have To Change The Catalytic Converter

its the Catty, baby.

Remember to back to the same test facility after the repairs have been done - they should only charge you $17 or something for the re-test
