I just got my 1990 Dodge Dynasty inspected and failed for emissions. I
failed for the NOx reading. On the sheet they gave me, the standard NOx
reading is 1273 and my car read 1357. Therefore, I failed. The HC reading
was fine and the CO% reading was fine. I don't know what can be wrong with
my car to affect the NOx reading. I don't have much money for repairs and
it's the only car I have. Any information about what needs to be checked
would be greatly appreciated.
