1991 Nissan Stanza Failed Emision Test in Metro-DC.
I have a Nissan Stanza 1991. It passed Emission tests since I got it in 2001. But this year it failed in all the three tests NOx, HC, and CO. The car has 197K+ on it. I change the O2 more than a year ago (I got the BOSCH universal O2 sensor on it). Oil was due to be changed by the time of the test but I didn't change it. I have never changed the CAT on it. By the way, does the CAT get fixed or they just need to be replaced? (Excuse my ignorance). I noticed before sometime before the test some blue smog coming out of the exhaust when I start it but it goes away in a little while. I had put in the fuel tank a bottle of some Smog Reduction additives. It was already in the tank the car test with. |

After you do a tune up or whatever, before you go take the test take
one bottle of dry gas (isopropyl alcolhol) and dump it in the tank. I haven't had a car fail yet.. I have a 89 Cutlas Cierra w/ 170k and it passed with flying colors and I don't do squat to it.
