You admitted you dont know anything, Ill give you credit there.
My tip on how to learn, is just pick up any car magazine you want and read it cover to cover. And then take all the stuff you dont know about that you find in the mag, and plug it into Google. Learn what it is and how it works. Then once you understand that first mag, go get another and start over.
No one here is gunna spoon feed you, but theres tons of knowledge here. To tap into you need to let us know that your actually tryin. GL.
