I have notice that alot of people here post error codes that really seem to help to find problems.
1. how do you find these codes? I it a hand held computer that you can buy at a local automotive store ?

2.If so which one would I buy and how much do they cost, also what is the best one to buy?

3. one more question , where would you plug it in?

Thanks again for all your help here guys, Ive saved alot of money by just reading some of the posts here and fixing problems myself, it's amazing how so many of us have the same problems with the same vehicle.
I guess it's a good thing at least this way we dont have to spend a crazy amount of money for someone to tell us to top our brake fluid off....
