IACV or Catalytic Converter?

Asked by Jun 10, 2012 at 11:39 AM about the 1999 Subaru Legacy 4 Dr L AWD Wagon

Question type: Maintenance & Repair

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.

I don't think the idle would be affected by the catalytic converter.
