What causes your car to run rich? I have an intake and an exhaust. The CAT is stock. The car runs fine no problems with it. And I just had a tune up about 20,000 miles ago. The last time I went through inspection I passed for emmissions. What could be the problem?

Thank you so much. Someone on the phone just told me the same thing and I didn't believe them because they don't know much about cars. But since I've seen your posts and car before it seems like you know what your talking about. I'll check into it. Also there's a post about universal O2 sensors do you know much about hem? Are they worth getting? Thanks again.
