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?

    My wife and I love our 2005 LaCrosse CXL. I recommend that you take it to a dealer, have them fix it, and enjoy the car!

    Is it normal for a1993 buick century custom (w/3.3 L engine)which i bought 3 years ago w\17K miles on it from an 83 old lady who owned & maintained it 100% by buick. It now has 47K miles on it. Since i bought it the engine had a rough Idle (or as Buick called it (LOPING) and said it is normal for that engine after checking it w/thier diagnostics equipment. Prior to going to Buick I have had it checked by several other auto mechs. they replaced the harmonic balancer cleaned and checked fuel injectors relaced plugs etc. Engine still idles rough. Is this NORMAL???

    That is, I believe, a 90 degree V-6. I'm not sure if it has a counterbalance shaft in it or not. If not, it would be normal for there to be some shaking at idle, as it is almost like a V-8 running with 2 dead cylendars. I suppose it depends on your definition of rough.

    Can a counter balance shaft be installed in a 1993 buick 3.3L engine if it does not have one? How much would it cost

    No. It is integral to the design of the engine.
