I recently purchased a 2006 cxs from my relative. This car has been neglected and I did this as a favor. It has a check engine light on. I had my friend hook up his obd2 system to it and he said that it gave back 2 codes which said the fuel mixture was to rich in #2 cylinder. Is this worth getting into or should I try to sell it. I love the way it drives and its more comfortable than my malibu maxx. I would hate to part with it after having it only 2 weeks. Any suggestions?
