    Took car to Auto Zone for diagnostic check. Below is a copy of what I was given.

    Definition: Catalyst efficiency low - bank 1
    The oxygen sensors monitor the catalytic converters ability to store oxygen.
    Probable causes:
    1. - Catalytic converter defective (Failure possibly due to #2, 3, or 4.)
    2. - Engine misfire or running condition
    3. - Large vacuum leak
    4. - Engine oil leakage into exhaust - valve guide seals, piston rings.

    I would greatly appreciate it if you could tell me what to check, or what the problem may be.

    Store Oxygen? Wow. Guess if he drove into the drink, and sunk, he could use the cats as rebreathers. Unbelievable. Funny.

    Thanks for the FixYa.

93 Plymouth voyager failed smog with high NOX .I've replaced transducer and EGR . The EG R was used and works . No check eng lite on but did pull codes #34+43+55

Although I could not find those specific codes, the grouping centers on various faults to the oxygen sensor, which was my first guess when I read about the high NOX levels. My local Advance Auto stocks the Denso direct fit oxygen sensor (Part No. 234-4004) for the 3.3 liter V-6 for $50.

Yes, it comes out the top. A 3/8 inch drive metric socket set will do. Depending on which engine you have (overhead cam? dual overhead cam?) and transmission (manual or auto), you may need to remove some parts to gain access. I can be more specific if you give me specifics on the engine and trans. I also recommend you browse my post at

1998 Plymouth Breeze 2.4 liter - Failed inspection

your O2 sensor up stream is gone and the engine is sucking air probably your pcv valve hose and is sucking oil straight into head and out D tail pipe! you have some good looking over to do on this by the sounds of it but do you notice oil missing a lot or do you bother to check and I would do a compression check on it before I spend any more cash on it!!! so start with compression test! see specks on line for suggested test pounds 145 pound per cylinder???net
