I just did an emissions test and even though my car passed i'm still conserned about something. The area where it says HC ppm and the limit is 69 my reading was at the limit. The guy that did the test told me that I should have done an oil change, changed the plugs, and change the air filter. The problem is my plugs are about a year old, I did an oil change at Chucks just before the test and my filter is about five months old. My question is what else could be affecting this. I can't help but wonder if my car could be running better than it is now. Any help would be appriciated.
