Smog check barely passed

[nrozett]

I just had my 1991 Acura Integra smogged. It passed with the numbers above average. The CO % at the higher (25) rpm was at the max (0.65). What should I look at to bring this number down? I have attached my emission test results if that helps you. thanks in advance.

there is nothing wrong with this as long as it passed.

the 2nd gen cars d not have an EGR valve so you tend to see higher CO2 & NO numbers. the only thing there is for Smog is the catlytic converter. That said once you get to where you fail... that is the only thing to replace.

in other words... you are good
