Failed echeck in Ohio

I have a 1991 Integra LS and it failed the Echeck in Ohio .I was wondering if a cold air intake would help pass or not. It said the CO levels failed, I guess that is the emissions. I need some advice before I spend twoo hundred on an intkae that may nto help. Thanks

Intake won't help - you probably need a new cat. converter. Replacing the PCV with help also.

not my usual forums, but moved.

fill ur gas tank up with premuim gas becasue it burns better and keep your car idoling/rev a bit until u go in it helps alot to.....my car failed its test and its a 90 shadow and sum guy told me this i ddiid it and it passed with out changeing n e thing

I feel your pain, I also live in Ohio. You don't even need to buy premium gas, just put a can of octane booster or "dry gas" in you tank. On your way to the echeck, just drive hard/take the long way. Let all of that carbon get out, that has worked for my when my 90 accord failed a few years back.
