Failed NOX Test

Chris · Sep 11, 2007

I have a 1994 Mazda B3000. I failed my NOX emissions yesterday. The standard is 3.0 and my truck is at 3.30. A mechanic told my buddy to use a bottle of rubbing alcohol in an old Bronco with the same problem and it worked. If I add a bottle of rubbing alcohol to a quater tank of premium gas would that fix the problem?

it should work.

i would recommend fixing the problem properly, however. NOX emission issues are usually in the EGR system...which can effect power, fuel economy, and driveability if not functioning properly.
