SRK Posted January 5, 2014 Share Posted January 5, 2014 You're going to have to provide more information, like the symptoms, and how you believe it's rich. Any codes? Any power loss? Trac off? That kind of thing. Quote Link to comment Share on other sites More sharing options...

SRK Posted January 5, 2014 Share Posted January 5, 2014 So if you have a check engine light you may have a bad O2 sensor. If the engine has no power and the cats are glowing then you may have a bad ignition coil- one of the two. You'll need to diagnose it further to be sure it is one of those items, or something else.
