Aright, i have gone 3 times and i have failed every time. My first time my Hydro carbons were 1.8 and it needs to be 0.800, and nox was 2.2 and needs to be 2.0. The second time i put this fluid in my gas and got 1.7 in hydro carbons and 2.4 on nox. SO i tried getting it really hot for the third time and got 6.6 for hydro carbons which made me fail, and passed the rest of it with flying colors. Does anybody have some suggestions on how to lower my hyrdo carbons without having to pay a lot of cash, so i can stop going to that stupid place. thanks
