So I failed smog the other day.. its a 92 accord ex 5speed.. everything was fine as far as CO & HC's.. the problem I had was with NOX.. @ 15mph it failed by 200 points and @ 25 mph it failed by almost 500 points.. the smog guy said he thought it might b the cat since it is an old car.. so my dumb ass replaced it and it turns out my reedings worsened.. the car didn't even pass the pretest after I put in the new cat.. has anyone had problems like this b4?

how old/new is your o2 sensor? does the smog test paperwork indicate what your timing was set to?1993 Accord DX | Rosewood Brown Metallic

depending on your co2% your o2 sensor change will proabably do nothing with nox.
NoX is oxides of nitrogen and usually is a indication of clogged egr ports or in some cases running lean from an advance in timing.
post all your numbers.What makes me laugh about forums, is that no matter how much you try to help someone, they dont take the advice. Go ahead and do it the hard way.
You got to respect what you drive, and appreciate what you have, making the best of what you got. and if that means putting CAI, HID's, a phat stereo system, and a idiot in the drivers seat...then so be it!
