NO is nitrous oxide, but why it is high is beyond my knowledge. I know without my main cat when I was on the dyno that number was well over 4000 for me. ---

my etest is fake, and probably 60-75% of everyone elses on here… and NO is not nitrus oxide NOx is caused by high combustion chamber temps. lmao… VIN: JN1MS34S8MWxxxxxx Year: 1991 Make: NISSAN Model: 240SX Engine Size: 2.4 Cylinders: 4 Test Date Test Result Sep 30, 2006 - Conditional Pass Sep 30, 2006 - Fail Almost time for another test…not lookin forward to what it says now lol ---

what over high combustion temps? get sa cooling system flush and pull the thermostat out too. then put some gas line antifreeze in the tank. it’ll burn cooler but not pooch the test but…it may convert some Nox to Cox’s (thats carbonic oxides you perverts) some of the Cox’s aren’t even tested for ---

I changed the Cat and passed with flying colors \*\* DO NOT USE THE PASS GARUNTEE can, you have to drive for something like 400k to clean it out of the system before you take the test, and it might f-up your cat in the end’ To change the cat only cost me $200 taxes in and install included at Zoro in mississauga. To get a fake pass would have been $250. I spent $250 but i have a new cat. Then i blew the clutch, but that’s another topic LOL
