Question

J-Integra, 1.8L 4 Cylinder, Atlanta, GA, May 25, 2012, 09:05
 Rookie

Have replaced 3 cats on this car at mileage interevals of 120K , 150K and at 172K. Muffler Shop told me Cats are failing because the front and rear oxygen sensors need to repaced. Did so on their recommendation and new cat replaced. Cat failed after 3K, now on 4th Cat converter. Muffler Shop told me that it is something wrong with the car and to take it to a Honda/ Acura shop. Please advise, car is running Great! Thanks, Jack

    Could be you have a faulty leaking fuel injector or a faulty Air Mass sensor or any number of possible senarios. A good technicinian can diagnose to determine is there is another problem that is causing cats to fail. Also if you are having aftermarket less costly cat converters installed that in itself could be a major part of your problem. Cheap replacemement Cats do not satisfy the emmision standards due to having much less of the platiumin that the oriqinal equipment Cats have.
