she really hasnt drove it in 4 months, and when she took it down she really didnt blow the car out on the freeway. See anything in the #'s that could cause the reason for fail?

im fairly sure my mustang doesnt pollute that much..

not sure on what causes cars to fail smog but since ive got off road cats and a couple things missing i just take it someplace where they guarantee a pass

NOx is likely that the EGR isn't opening, I'd check it out and what controls it.

if the EGR checks out, then it could be the cats need replacing.

either egr is not working properly or there is alot of carbon build up on the pistons
