This car runs great but the NOx levels are way over the roof. I was wondering what should I do to fix this issue. I installed a new CAT and exhaust system is new too. What are my options. Would really appreciate help.

thanks,
Kenny

It's very likely your EGR. Take the EGR valve off with the pipe and all hoses. You will see a lot of carbon deposits and probably clogging the pipe/hoses. Clean them up, you should be good to go.

Try the stickies at the top of the Camry forum. If not, check out Autozone's website for removal/installation instructions for your year.
