Hello, We`purchased a 2008 EOS (used)aprox. 6 months ago . It's a great car . Aprox. 28000 miles on it now. Today @13* F I went out and started to warm up and it acted like the choke was stuck on (At least thats what I would have said if it was my truck) . I shut it off and restarted it and it ran fine but the EPC light was on . I looked it up and it mentions the cat . converter pos. damage or prob. Will this clear itself or must be address at the dealer? We use high octane fuel and have it serviced reg. I was kinda puzzled that this type of prob. would occur at such a low milage car. Any info or feed back is appreciated. I don't want to cause further damage. Thanks in advance . Van
