So I went to dmv the other day to get my car tagged, and when they did the emissions test on my car it failed the idle hydrocarbon test. I'm running a high flow cat so I didnt think this would happen. I think the guy messed up the test though. He started doing the low test and the RPM reader messed up so he went on to do the higher RPM test then when back to the low RPM test, the second time He did the low test the HC was higher. I think I just need to run the car out a little but does anyone have anyother suggestions?
