If a Honda engine dies at 200k, something is really wrong. Abuse or neglect. I have a VX with over 300k, easily passes emissions, 49mpg city and no signs of wearing out. I have an 88 CRX Si, also 300k. Hauls ass for a stock D series. Passing emissions is a breeze. These two cars are the 11th and 12th Hondas that I've owned.

hey guys I need a little help also. my car failed smog and I have no idea why. here's the readings
15mph/25mph
CO
14.2/15.1
O2
0.6/0.2
HC
182/67
CO
.76/.19
NO
2477/195
the car has a brand new Catalytic Converter, an o2 sensor which is less than a year old, fresh spark plugs, oil, wires, cap, n rotor.
any help would be appreciated.

Ahoy! I didn't pass smog at 15mph wondering if you could point me in the right direction. I'm in California. I'll keep this as short as possible.
Its a 1992 honda Civic 4 door manual with 230,000 miles on it. It seems to run pretty good and it passed smog just before I left and only has 4,000 miles since it passed smog 5 years before. Apparently the Cat is really rusted and I did run some of the 5 year old fuel in it just before the tune up.
My car sat for 5 years without being run as I was living outside the country. I did a few things before smoging it (oil change, valve cover, air filter) . I emptied the old fuel and added higher octane (thinking it might help?) and ran lucas fuel cleaner. I passed on my 25mph but not on 15mph and passed on all of the C02. Also reading doctor google someone said it could be O2 sensor so I replaced that and went from 1800(NO) ppm to 1463 (NO)ppm.
For my 15mph
HC (PPM) = 144 Max 96
Co (%) = .37 Max .59
NO (PPM) = 1463 Max 859
For my 25mph
HC (ppm) = 52 Max 79
Co (%) = .34 Max .51
NO (PPM) = 360 Max 798
Before speculate or listen to others speculate what do you think about the numbers? Also there was a tiny crack on top of the air filter box that I put a piece of tape over and it passed all visuals.
Thanks so much! I really don't want to take it to a mechanic as the car is likely worth less then what a mechanic would charge to fix.
