As a woman, many men look at me like I'm some freak of nature when I can tell them what is wrong with my car when it breaks down. That little check engine light can tell a person quite a bit if you know how to find out why it is on. I bought this little computer thing that plugs into my car and tells me what error code is causing the check engine light to come on. Once I have a code, the problems are usually pretty easy to fix. If your check engine light is on, this blog can help you find the reason and make the repairs.
