I got fuel in the cat. The cat. Is broken.
Can that be caused by a malfunction of the idle air control valve?
What else can it be caused by?

Thank you,

I recommend you check the fuel injectors and fuel pressure regulator if its leaking-if not could be coming from the oxygen sensors/CTS staying in the open loop mode and computer giving fule when not needed.
