1995 Taurus SHO, 3.0L, 6cyl, 122,000mis
High NOx levels on emissions. Checked, replaced or cleaned everything I could. My uncle says it is either a vacuum leak or the catalytic converter. Don't want to mess with the Catalytic Converter, but I can check for a vacuum leak. How do I do that?
have the same problem?
