    My car is still at the dealer from the 10th of January. They "Think" the catalytic converter will be in by the end of March.

    Damn. Can't be driven in the mean time? Maybe you should try to locate one for them.

    I had planned to sell it and buy a new V but I think I may end up keeping it. As for driving it no. Its failed that bad.

    Re: It happened again!!

    Agreed. I had a cat fail and once the dealership diagnosed it and ordered the part they told me to come pick up the car. Why wait 6 weeks (which is absurd, I got the part in 11 days) with your car sitting in a parking lot when nothing is mechanically wrong with it. To hell with mother nature, she can suck on your extra NOx gases until the part is delivered.

    Re: It happened again!!

    if its bad enough to cause misfiring I wouldn't drive it. (assuming 'clogged' cat)

    After looking up the DTCs it states:
    Important: A new converter with less than 100 miles on it may set DTC P0420 or P0430 due to out-gassing of the internal matting.
    Operating the vehicle at highway speeds for approximately 1 hour may correct the condition.

    It also mentions this:

    Repair Verification

    1. Clear all DTCs.
    2. Allow the engine coolant temperature to reach 70°C (156°F).
    - Place the gear selector in Park, Neutral for manual.
    - Set the parking brake.
    3. Press and hold the service brake.
    4. Run the engine for 6 minutes at 2,500 RPM.
    5. Allow engine speed to return to idle speed, then place gear selector into Drive, or apply clutch pedal for manual.
    6. After 2 minutes, verify that DTC P0420 or P0430 have passed or failed this ignition cycle.
    ¤ If not passed or failed this ignition cycle, the test aborted resulting in an inconclusive test result. The above test may need to be repeated up to 5 more times during this drive cycle.
    ¤ The first test should be run after the initial warm up period of 6 minutes. Between subsequent tests, maintain 2,500 RPM for 2 minutes.
    7. If 6 tests have been attempted and the DTC has not run or passed during this key cycle, turn the key to OFF for 30 seconds, then run the procedure a second time.

    Re: It happened again!!

    Just got back from Kachina with a new Passenger side Cat and Manifold. So those of you waiting for one should get it soon!

    Now I have to adjust the MAF table AGAIN............ The bad cat was causing a false lean condition. Good thing it was actually rich....

    My part came in on the truck that morning with the "overnight" shipment. They had it on in less then 6 hours. Good work but they didnt need to rush. lol

    Re: It happened again!!

    Yea, that is what I told the dealer. Can high efficiency cats be adapted
    to your headers. I live in a lifetime smog state unfortunately. Let me know.

    You can have them added to the exhaust right after the headers.
