So someone gave me a 2007 Ford Taurus and I was taking it to a mechanic to have the tires changed when the check engine light came on. I had them scan it and they said it was a Bank 1 something or another code. Oxygen sensor or cat code but I didn't get the actual code and will have to try to get the actual code from autozone or the like. My mechanic said not to worry about it but I don't think the check engine light will go off by itself. I want it to go off and think that maybe I can fix it myself. Can anybody point me in the direction of a good car forum that, like this forum, will be kind to a novice mechanic?
