    hold it at about 2500 rev for bout 5 minute and that will give ecu time to reconfig with the lambda sensor to get all the fueling rite again

    the cat needs to be hot before it will do anything productive so a long hard drive before the emissions is the best idea.
    Put a whole bottle of redex fuel cleaner into 1/6 or less of a tank and be amazed
