The reason JDM vehicles (like my MR2) have such high NO2 #s is because they don't have an EGR valve, my MR2 numbers looked exactly the same.

And I didn't need to elaborate, the answer is quick and simple! Something to do with the EGR system is messing up Now I could have said, "use the search option because people have brought this up numerous times and there is a huge post on e-test numbers, so you should do that because I am going to be a dick to you if you don't", but I thought just saying the answer would be best
