Hey guys I just failed emmission test today .
I failed and I don't know what's the cause. I failed the part called oxides of nitrogen ( something like that) .
Can anybody tell me what should I do with this in order to pass the test?

Once again i ask why then? because it doesnt seem like he has mods where he would need to do any tricking of the o2 sensor. Unless he is catless, which is just dumb.
I say get rid of the stupid o2 trick, then put the stock one back it, drive it around and re-test, if you still fail, then check your egr valve

Ya, the only thing that is doing is tricking your ecu from sending out a check engine code... But in reality you arent ever gonna pass an emisions test... Just b/c you trick your ecu doesnt mean its up to code

True that on the tricking the ECU. I almost pass the emmission. Nox fail because I was 2.5#### and the passing point is 2.1####
someone told me to put 2 cans of dry gas , take off air filter and drive the car on highway for 20 minutes at least before the test
What do you guys think? I have 4 months to come up with something.

It is a valve that recirculates some air from the exhuast back into the engine (Exhuast Gas Recirculation Valve) Alot of times when the start to get clogged, or go bad you will start to see higher emmisions #'s. And i believe NOx is one that it would mess up. But you could also try the dry gas, that will reduce your #'s a bit
