    232-Long term fuel trim,idling
    435-Front HO2S slow response
    443-TWC efficiency, (three way catalytic converter)
    Fault source most likely air leakage, check vacuum hoses and vacuum tower behind throttle cover and IAC valve. All three codes are most likely set by the leak.

    Go to this website for lots of information on codes and vacumn leaks. 232 is a fuel trim, 435 is a front 02 sensor, I don't know about the other.

    Another good site is:

    http://au.geocities.com/ozbrick850/

    On the ozbrick link there are several tables of codes for different systems.

    Sounds like your problem might be a vacumn leak. Check the elbows before spending the money on 02 sensors.
