Failed E-test!!!!
Ok...subject car is a 1992 honda civic DX BONE stock.....no mods at all....
I passed everything but the NO under load at 40 km/hr.
Limit was 636, I shot to kill at a whopping 1253...
I know a high oxides of nitrogen reading is generally a symptom of a high heat/lean burn condition....
my air filter is good, correct plugs are in the car, no intake restriction etc.
Could the culprit be my cat? And is it possible that the e-tester didnt warm my car up enough so the cat would reach its proper light-off temperature?
Thanks for your help!

retard your timing a few degrees on the distributor that will lower it
use a timing light to reatrd i would say 3-5 degrees
then after you are done if it doesnt feel as peppy, change it back...

Make sure your car is nice and hot when you go there and Run some 94 octane. And if it still fails than just get a fake one

higher octane gas and retarded timing are just band-aid solutions for a more serious underlying problem. clearly your car has something wrong, and you need to address the issue at the source. replacing parts you or anyone here 'think' may be bad is a bloody waste of money. clearly this is outside the perimeter of your abilities, I would say the money wasted replacing working parts based on our intuition is better spent on a mechanic who will diagnose the problem correctly. Buddah here on this site is a cert. emissions inspector and I'm sure he can diagnose the problem and correct it at a fair price. better than throwing money at an unknown problem. high NOX could even be caused by excessive carbon buildup in the engine causing pre-ignition or something obscure like that. clearly you have read up on this problem and you know a lil bit, but don't mistake yourself for a mechanic.
