IACV or Catalytic Converter?
How do I know if my idling problem is the IACV (threw that code when hooked to machine) or the catalytic converter that a retired mechanic suggested it could be? I live in an extremely small town with limited mechanics and no one here just will assess the situation. They just keep replacing things and hope it fixes it and I can not afford to do that. The car idles very rough at standstill and when accelerating, seems to take a bit to get to speed. Help! I am a single parent and this is my only vehicle. I need a suggestion as to what to ask so I do not get ripped off. Thanks.
