So, my Maxima *just* missed passing emissions last time. MD tests 3 things, NOx, CO, and HC. HC it passed but NOx and CO it was just out of spec on. I don't have the specific numbers here, but I could get them if it would be helpful. Any suggestions about what I can do to help the car pass? I am already planning to install a new O2 sensor (car probably needs it anyway), and the car had a new pre-cat and cat about 2 years ago. AFAIK they are still good. I've heard that a little alcohol in the gas tank will help. Any truth to it? Any other tricks like that? Like I said, it was close so just a little "bump" would probably do it.
TIA This post has been edited by BigEnos: Mar 9 2006, 04:55 PM |

TIA Had you changed the oil recently? Remember how much the #'s dropped on the old A.I. van when we changed the oil. Granted, nobody could remember when/if the oil was last changed in 10 years of club ownership. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) I tried one of those "guarantee to pass" bottles from Advanced Pep Zone in my Firebird a few years ago. Didn't affect the #'s one bit. In my Nissan, the EGR is right on top of the intake manifold so it's pretty easy to check. I took it off my old raSEcaR and it was pretty gunked up. Otherwise, plugs, wires, dist cap/rotor, O2, PCV, clean TB, etc. Pat This post has been edited by patred: Mar 10 2006, 09:02 PM |
