I took my car to get a smog check done and it failed the No(ppm) of the test. The guy at the shop told me If i wanted it to pass that I needed to replace the catalytic converter but I read on another website that high NOx numbers happen when the egr valve is not working properly. I only have one free retest so do I replace the cat and clean the egr?
